Updated November 4, 2026
Getting "CODBrokerInstaller.exe did not receive required authorization" when launching Call of Duty: Modern Warfare 4 on PC?
You might also see "BIOS Firmware Update Required," "Failed Attestation Status," or a security warning even though TPM 2.0 and Secure Boot are already enabled.
These messages can look similar, but they do not always have the same cause. A missing Windows administrator prompt is different from incompatible TPM firmware or a failed security-attestation check.
The good news is that you can diagnose most of these problems without immediately reinstalling Windows, clearing your TPM, or changing motherboard firmware.
This guide covers the safest troubleshooting steps first, explains which fixes match each error, and shows you when a BIOS update may actually be necessary.
Quick Answer: Fix CODBrokerInstaller.exe Authorization Declined
If MW4 displays "CODBrokerInstaller.exe did not receive required authorization," try these steps in order:
- Restore Windows UAC prompts. Open Change User Account Control settings and make sure administrator notifications are enabled.
- Restart Call of Duty. Approve any legitimate authorization request for CODBrokerInstaller.exe or enrollaik.exe.
- Check COD Broker Service. If the service exists, verify that it is not disabled.
- Run the official Secure Attestation Wizard. Download it from Activision and check which security requirement fails.
- Verify TPM 2.0 and Secure Boot. Use tpm.msc and msinfo32.
- Check TPM firmware compatibility. Certain AMD and Intel firmware versions may require a motherboard BIOS update.
- Update compatible chipset drivers. This may help when the hardware security checks pass but attestation still fails.
- Repair Windows system files. Use DISM and System File Checker if the problem continues.
Start here: If the message specifically says authorization was declined, check Windows UAC before updating BIOS.
A firmware warning does not automatically mean your motherboard is incompatible or that the game is completely unplayable.

What Does CODBrokerInstaller.exe Authorization Declined Mean?
CODBrokerInstaller.exe is associated with Call of Duty's security authorization process.
The game uses hardware and Windows security checks to verify that your PC meets its requirements.
If the required authorization does not complete, you may receive:
"CODBrokerInstaller.exe did not receive required authorization."
Possible causes include:
- Windows does not display the administrator permission prompt.
- The authorization request was dismissed or declined.
- A required security service is disabled.
- The game's security registration cannot complete.
- TPM or Secure Boot requirements are not satisfied.
- The system fails a separate attestation check.
An authorization failure does not automatically mean your BIOS is outdated.
If MW4 launches successfully but suffers from freezing or poor performance, see our MW4 DMZ stuttering and FPS drops fixes. Those problems require different troubleshooting.
Which MW4 Error Are You Getting?
Use this table to identify the most relevant fix before changing anything.
Important: A BIOS firmware warning and Failed Attestation Status are not necessarily equivalent to a complete launch failure.
Depending on your security compliance status, some playlists or game modes may be restricted, and matchmaking may place your account in a separate pool.
Fix 1: Restore the Missing Windows UAC Prompt
This is the first fix to try when MW4 says authorization was declined but Windows never asked you to approve anything.
Windows User Account Control (UAC) displays administrator authorization requests when applications need elevated permissions.
If these notifications are disabled or suppressed, the game's security registration may not finish.
How to enable UAC notifications
- Close Modern Warfare 4.
- Open the Windows Start menu.
- Search for Change User Account Control settings.
- Open the result.
- Check the notification slider.
- Select the default notification level or temporarily choose Always notify.
- Click OK.
- Restart Windows if prompted.
- Launch Call of Duty again.
Watch for an administrator permission request involving:
- CODBrokerInstaller.exe
- enrollaik.exe
If the prompt belongs to your legitimate Call of Duty installation, approve it using the appropriate administrator credentials.
Do not approve an unfamiliar executable based only on its filename.
What if the prompt still does not appear?
Try restarting Windows and launching the game through Steam or Battle.net again.
Also confirm that your Windows account can provide administrator authorization.
If the PC is managed by a school, employer, or another administrator, security policies may prevent the required prompt from appearing.
Do not permanently disable UAC to fix the game.
Fix 2: Check COD Broker Service
If the authorization error continues, check whether the Call of Duty Broker service is available.
A disabled service may interfere with the security authorization process.
How to check the service
- Press Win + R.
- Type services.msc.
- Press Enter.
- Look for COD.Broker.Service.
- Double-click the service if it appears.
- Check its Startup type and Service status.
If the service is disabled, setting it to Manual and starting it may help on some systems.
This is a conditional workaround, not a guaranteed fix.
Before changing anything, record the original service settings.
If the service is already running, leave it alone and continue to the next fix.
Do not disable unrelated Windows security services.
Fix 3: Download and Run the Secure Attestation Wizard
The Call of Duty Secure Attestation Wizard is the most useful diagnostic tool when TPM 2.0 and Secure Boot appear enabled but the game still reports Failed Attestation Status.
Unlike an ordinary in-game settings menu, this is a standalone utility provided by Activision.
How to download the official wizard
- Visit the official Call of Duty TPM 2.0 and Secure Boot support page.
- Find the Call of Duty Secure Attestation Wizard section.
- Download the latest available wizard ZIP file.
- Extract the ZIP file to a folder.
- Open the extracted folder.
- Double-click CODSecureAttestationWizard.exe.
- Accept the terms and run the scan.
- Wait for the results.
The wizard checks whether your PC meets the required security configuration.
Understanding the results
System compliant
Your PC meets the security requirements checked by the wizard.
If MW4 still displays an authorization error, investigate UAC prompts, the Broker service, and other game-specific registration problems.
System not compliant
The wizard identifies settings or components that need attention.
These may include TPM, Secure Boot, BIOS firmware, or other security requirements.
Follow the specific failed check rather than changing unrelated settings.
What if you see TCG Event Log Failed?
Restart Windows and install the latest available Windows updates.
Then run the wizard again.
If the warning persists, check the motherboard manufacturer's support information.
Fix 4: Check TPM 2.0 and Secure Boot
Even when TPM and Secure Boot are enabled in BIOS, Windows must recognize them correctly.
Check TPM 2.0
- Press Win + R.
- Type tpm.msc.
- Press Enter.
- Look for the Status section.
- Check Specification Version.
A correctly configured TPM 2.0 system should normally report:
- The TPM is ready for use
- Specification Version: 2.0
Also note the Manufacturer Version under TPM Manufacturer Information.
You will need that number when checking firmware compatibility.
Check Secure Boot
- Press Win + R.
- Type msinfo32.
- Press Enter.
- Find BIOS Mode.
- Find Secure Boot State.
The expected configuration is:
- BIOS Mode: UEFI
- Secure Boot State: On
If Secure Boot is disabled, consult your motherboard manufacturer's instructions.
Do not randomly change boot modes, disk partition settings, or firmware security options.
Incorrect changes can prevent Windows from starting.
What if both checks pass?
TPM and Secure Boot are only part of the overall attestation process.
A system can pass these checks while still having a firmware compatibility, authorization, or registration problem.
Continue with the next relevant fixes.
Fix 5: Check Windows Memory Integrity
Windows Memory Integrity is a security feature found under Core isolation.
Enabling it may help some systems experiencing persistent security-attestation failures, but it is not a guaranteed fix or a universal Call of Duty requirement.
How to check Memory Integrity
- Open Windows Security.
- Select Device security.
- Open Core isolation details.
- Find Memory integrity.
- Check whether it is enabled.
If Memory Integrity is disabled and Windows reports no incompatible drivers, you can consider enabling it.
Restart Windows if prompted, then retest MW4.
What if incompatible drivers are detected?
Do not force the setting.
Instead, identify the incompatible driver and look for an updated version from its manufacturer.
If the feature cannot be enabled safely, continue with the other troubleshooting steps.
Fix 6: Update Motherboard Chipset Drivers
Outdated chipset drivers can sometimes contribute to compatibility problems involving Windows and motherboard security features.
Updating them is worth considering when TPM and Secure Boot appear correctly configured but attestation still fails.
How to update chipset drivers
- Identify your motherboard or laptop model.
- Visit the manufacturer's official support website.
- Open its driver download section.
- Select your Windows version.
- Find the latest compatible chipset driver package.
- Download and install it.
- Restart Windows.
- Run the Secure Attestation Wizard again.
AMD users can also check the official AMD Drivers and Support page.
Important: Updating chipset drivers does not update your motherboard BIOS or TPM firmware.
If the error continues, check your TPM Manufacturer Version before deciding whether a BIOS update is needed.
Fix 7: Check AMD and Intel TPM Firmware
Some TPM firmware versions do not meet Call of Duty's attestation requirements.
This is especially important if the game displays BIOS Firmware Update Required despite TPM 2.0 being enabled.
How to find your TPM Manufacturer Version
- Press Win + R.
- Type tpm.msc.
- Press Enter.
- Find TPM Manufacturer Information.
- Read Manufacturer Version.
Compare the reported version with the compatibility information below.
AMD TPM firmware compatibility
Certain AMD TPM firmware versions matching this pattern require an update:
3.*.0.*
The asterisks represent variable version numbers.
For example:
Notice that both versions begin with 3.92.
The important difference is the full firmware version, not just the first two numbers.
If your AMD TPM firmware matches the incompatible pattern, check whether your motherboard manufacturer provides an appropriate BIOS update.
For additional information, see AMD's TPM firmware compatibility guidance.
Intel TPM firmware compatibility
Certain Intel TPM Manufacturer Versions may also require firmware updates.
Relevant patterns include:
- INTC 302.12.*.*
- INTC 303.12.*.*
If your system matches one of these patterns, contact the motherboard or PC manufacturer to confirm whether an update is available.
Do not install firmware intended for another motherboard or system.
Does incompatible TPM firmware mean you need new hardware?
Not necessarily.
A compatible BIOS update may resolve the problem.
Replacing your motherboard or CPU should not be the first troubleshooting step.
Fix 8: Update Your BIOS Safely
A BIOS update may be necessary if your motherboard uses incompatible TPM firmware or the manufacturer provides a specific security compatibility fix.
However, BIOS updates carry more risk than ordinary software troubleshooting.
Before updating BIOS
Make sure you:
- Identify the exact motherboard model.
- Confirm the hardware revision.
- Read the manufacturer's BIOS release notes.
- Verify that the update is intended for your hardware.
- Save your BitLocker or Device Encryption recovery key if encryption is enabled.
- Follow the manufacturer's update instructions.
- Ensure your PC has reliable power during the process.
Never install a BIOS file intended for a different motherboard revision.
Gigabyte A520M K V2 example
If your PC uses a Gigabyte A520M K V2 motherboard, identify its exact revision before downloading firmware.
Different revisions can use different BIOS releases.
Official support pages:
Check the release notes for TPM firmware and AMD compatibility changes.
Do not select a BIOS version solely because another player reported success with it.
After updating BIOS
- Restart Windows.
- Open tpm.msc.
- Check the TPM Manufacturer Version.
- Open msinfo32.
- Confirm Secure Boot remains enabled.
- Run the Secure Attestation Wizard again.
- Relaunch Call of Duty.
Some BIOS updates reset security settings, so verify them again after the update.
Do not clear your TPM as a routine fix. Clearing it can invalidate protected credentials and trigger BitLocker recovery.
Fix 9: Check Attestation Key Generation
Sometimes a BIOS update succeeds and TPM 2.0 passes, but the game still reports Failed Attestation Status.
This can happen when another part of the security registration process remains incomplete.
What to check
- Restart Windows after BIOS or chipset updates.
- Run the latest official Secure Attestation Wizard.
- Review the compliance result.
- Relaunch Call of Duty.
- Approve any legitimate administrator authorization prompt.
- Check whether the original error has changed or disappeared.
If a legitimate Call of Duty security interface explicitly offers an attestation-key generation or registration action, follow its displayed instructions.
However, do not assume that every version of the standalone Secure Attestation Wizard includes a Generate Key button.
What if registration still fails?
Avoid:
- Clearing the TPM without official guidance.
- Deleting security certificates or TPM credentials.
- Modifying sensitive TPM registry entries.
- Downloading unofficial attestation repair utilities.
If the system passes the wizard but still fails authorization, contact Activision Support with the exact error message.
Fix 10: Repair Windows System Files
Corrupted Windows system files can sometimes interfere with system services and security-related processes.
Windows includes built-in tools to check and repair these components.
Step 1: Run DISM
- Close Modern Warfare 4.
- Open the Windows Start menu.
- Search for Command Prompt.
- Select Run as administrator.
Enter the following command:
Press Enter.
Wait for the process to finish.
Step 2: Run System File Checker
In the same administrator Command Prompt, enter:
Press Enter and allow Windows to complete the scan.
If Windows repairs damaged files, restart your computer.
Then launch MW4 and repeat the relevant security checks.
These tools can repair Windows corruption, but they cannot guarantee a fix for incompatible TPM firmware.
What If COD Broker Service Is Missing?
If you cannot find COD.Broker.Service in Windows Services, first check whether the game installation is complete.
A missing service is different from a service that exists but is disabled.
Do not manually create the service using unfamiliar commands or download replacement executables from third-party websites.
Verify files on Steam
- Open Steam.
- Go to your Library.
- Right-click Call of Duty.
- Select Properties.
- Open Installed Files.
- Click Verify integrity of game files.
- Wait for verification to finish.
- Relaunch the game.
Repair files on Battle.net
- Open Battle.net.
- Select Call of Duty.
- Open the menu beside the Play button.
- Select Scan and Repair.
- Start the repair process.
- Wait for it to finish.
- Relaunch the game.
If the service is still missing, use official Call of Duty support resources for further assistance.
Failed Attestation vs Authorization Declined
These messages can appear together, but they refer to different parts of the security process.
Does Failed Attestation always block MW4?
Not necessarily.
A failed security-attestation status may restrict certain game modes, including Ranked Play, or place players into separate matchmaking pools.
A BIOS firmware warning may also appear before a firmware update becomes mandatory for full compliance.
The important thing is to identify the exact warning and follow the appropriate troubleshooting path.
What If Nothing Works?
If MW4 continues to display CODBrokerInstaller.exe authorization declined or Failed Attestation Status, complete these final checks:
- Restart Windows after security or driver changes.
- Install available Windows updates.
- Verify Call of Duty installation files.
- Check TPM Manufacturer Version.
- Confirm Secure Boot is enabled.
- Run the latest Secure Attestation Wizard.
- Record the exact error message.
Contact Activision Support
Visit Activision Support if authorization continues to fail.
Useful details to include are:
- Motherboard or laptop model.
- BIOS version.
- TPM Manufacturer Version.
- Windows version.
- Exact authorization or attestation error.
Never share passwords, BitLocker recovery keys, or other sensitive credentials.
Submit a Failed Attestation Report
If your system remains noncompliant after completing the recommended troubleshooting, you can review Activision's TPM Failed Attestation Report.
This form helps identify hardware and firmware configurations that may need further investigation.
Important: Submitting the report does not create an individual support ticket, and you should not expect a personal response.
If you have an AMD TPM firmware version matching 3.*.0.*, follow AMD and your motherboard manufacturer's firmware guidance instead of submitting that report.
Lenovo users with failed attestation should contact Lenovo Support for device-specific assistance.
Should you reinstall MW4?
A complete reinstall is worth considering only after the less disruptive troubleshooting steps have failed.
Reinstalling may repair missing game components, but it will not necessarily correct incompatible TPM firmware or Windows security settings.
If MW4 launches but displays broken textures, low-resolution graphics, or blurry visuals, see our Modern Warfare 4 pixelated or blurry graphics fixes instead.
Frequently Asked Questions
Why does MW4 say CODBrokerInstaller.exe did not receive required authorization?
A required security authorization step did not complete. Start by checking Windows UAC settings and approving legitimate administrator permission prompts.
How do I fix CODBrokerInstaller.exe without updating BIOS?
Restore UAC notifications, restart Call of Duty, check COD Broker Service, and run the official Secure Attestation Wizard. A BIOS update is not necessary for every authorization error.
Why does MW4 show Failed Attestation when TPM and Secure Boot are enabled?
TPM and Secure Boot are only part of the security validation process. Firmware compatibility, Windows configuration, or incomplete authorization may still prevent compliance.
Is AMD TPM firmware 3.92.0.5 compatible with MW4?
No. Version 3.92.0.5 matches the incompatible AMD TPM firmware pattern. Check your motherboard manufacturer's support page for a compatible BIOS update.
Is AMD TPM firmware 3.92.5.5 compatible?
Yes. Activision identifies 3.92.5.5 as a compatible example.
Can I play MW4 with Failed Attestation Status?
You may be able to access some features, but certain game modes or playlists can be restricted. Your account may also be placed in a separate matchmaking pool.
Why does MW4 still fail attestation after updating BIOS?
The BIOS update may have succeeded while another security requirement remains incomplete. Recheck TPM, Secure Boot, and the Secure Attestation Wizard results.
Should I clear my TPM to fix MW4?
No. Clearing the TPM is not a routine fix and may affect protected credentials or trigger BitLocker recovery. Use official manufacturer guidance before considering it.
Does reinstalling MW4 fix CODBrokerInstaller.exe errors?
It may help when game components are missing or damaged, but reinstalling does not guarantee a fix for Windows authorization or TPM firmware incompatibility.
Final Thoughts
If Modern Warfare 4 displays CODBrokerInstaller.exe Authorization Declined, start with Windows UAC settings and the Call of Duty Broker service.
For BIOS Firmware Update Required or Failed Attestation Status, run the official Secure Attestation Wizard and check TPM firmware compatibility before changing BIOS settings.
Most importantly, do not clear your TPM or flash unrelated BIOS firmware simply to remove a warning. Identify the exact failed security check and apply the appropriate fix.
