How to Fix Brother BrLog Errors
The most effective resolution for the “STI BrtSTI FindPushAwareAppName:: Invalid Arg” error is to delete the BrUtilities and PushScanApp registry folders located under HKEY_LOCAL_MACHINE\SOFTWARE\Brother
Simply uninstalling and reinstalling the Brother software suite often does not clear this issue because of the lingering registry keys which continue to trigger the error loop.
This article will guide you through the process that I used to prevent the BrLog error from triggering every single second on my Windows 11 PC.
Removing BrUtilities & PushScanApp
Note that this error is frequently caused by the Windows Image Acquisition (WIA) service attempting to communicate with broken or missing utilities, and while some users have tried disabling the WIA service, removing the offending registry keys is the preferred solution. See steps below.
Step 1
Open the Registry Editor (regedit), navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Brother, and delete the BrUtilities and PushScanApp subfolders.
Alternatively, you can download the registry editor script using the button below (at your own risk of course). Be sure to have a full system backup, just in case.
Step 2
Restart your PC and check your Event Viewer > Application logs to see if the issue persists.
If it does, use BrUtilities to uninstall all brother related devices, redo the registry edits, then download the latest drivers from the official Brother website and perform a fresh installation.
