You must run power shell with elevated privileges. Right click on the powershell application and select run as administrator.

[LukeDouglas2]

Yea, I did run it as Administrator. That's fairly standard procedure.

[pyrates999]

I checked the error code 0x800106ba, and it means you have another antivirus program active, which means you need to add those files and directories to be excluded in your antivirus program.

[LukeDouglas2]

Windows Defender is disabled. The only antivirus program running is Norton 360. I have C:\Program Files\ExplorerPatcher* excluded.

FYI, EP is running and working as expected. Was running these commands are recommend. Not sure they are truly needed.

[pyrates999]

You didn't read all the release notes here: https://github.com/valinet/ExplorerPatcher/releases

You also need to add these to be excluded to your antivirus:

• %APPDATA%\ExplorerPatcher
• C:\Windows\dxgi.dll
• C:\Windows\SystemApps\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy
• C:\Windows\SystemApps\ShellExperienceHost_cw5n1h2txyewy

And include the download directory that you download EP to as well.

[LukeDouglas2]

Excluded all. Disabled anti-virus. Same results.

Screw it. EP is working as before. I ain't worrying about this no more.

Then please close this issue.
