Can't run or install Plex on Win 10?

It ran fine on Win 7. On 10 using the latest update from Plex I get this error, "The installer has insufficient privileges to modify the file. C:\Program Data\Microsoft\Windows\Start Menu\Programs\Plex Media Server"

I uninstalled and deleted the registry key for Plex and the file system directory. I then re attempted the install with admin privileges. Unfortunately, it still failed with the same error.

Any suggestions?

Thanks,

Charley
