This was purchased and I have entered my license details. It activated successfully.
Ok so I can't uninstall AppGuard. I have checked "Stop self protection" and tried putting the slider to the "Off" mode and also tried stopping the service but every time I try to uninstall I get (even when logged in as my admin account):
Ok so I managed to uninstall but not using the "Programs & Features". I had to rerun the AppGuard installer and it then proceeded with the uninstall. I then rebooted and reinstalled and rebooted again but I am still getting the same errors when changing the slider. I've tried "Restore all settings to default" but even that errors with the same error I posted earlier. I uninstalled using my admin account but have only tried changing the slider with my SUA account.
I have set AppLocker to audit mode so it doesn't interfere. Nothings getting blocked in Event Viewer.
Ideas? Not sure what to try next. I don't have any other security products running except WFC but I have disabled my firewall temporarily while troubleshooting this.
You have to check all the file paths on your system to make sure there are none that will cause the policy error. A default install of Windows does not use characters such as "&" - at least not one that I have ever seen. It is still possible that a program would create a file path with characters, but in all cases that I have seen it has been file paths on non-system drives\partitions and user created file paths.
Use a utility such as UltraSearch or Search Everything to inspect folder file paths and names. When using one of those utilities, only enable a search of folders. Search for non-letter characters permitted by Windows in the folder names\file paths.
Also, mounted virtual drives, mapped network drives, and cloud storage that mounts as a drive can cause the error. Cloud storage that mounts a drive is not supported and will generate the same policy error.
