If you see it and want to fix the Windows 10 error ‘EXTERNAL EXCEPTION E06D7363’, here is what you need to do.

There are several causes for this error. Windows has a corrupted file another program wants to access or you’re trying to install a malware scanner over a previous installation.

Fix the Windows 10 EXTERNAL EXCEPTION E06D7363 error
The popular malware program MalwareBytes is a popular cause of this error and it has happened to me a couple of times so let’s deal with that first.

1. If you have installed MalwareBytes before, download the MalwareBytes Removal Tool.
2. Run the tool and uninstall MalwareBytes.
3. Reboot and retest.

If you don’t use MalwareBytes, check your system for other antivirus or malware scanning software. Uninstall using the program’s uninstaller and retest. Add it again once the error has been fixed.


If you haven’t used malware tools, we need to check Windows core files for corruption.

1. Open a CMD window as an administrator.
2. Type or paste ‘sfc /scannow’.
3. Let the process complete and make repairs if needed.

SFC scannow is a great app for finding file corruption but may need multiple passes to fix everything. You may also need to reboot into safe mode and try it from there.

If that doesn’t work, consider a system restore to a last known working configuration. There is a file lock or corruption somewhere and if SFC scannow doesn’t find it, troubleshooting further is a real challenge.
