I was trying to install CrashPlan for a specific user so I could backup a network mapped drive, this sucked I think at least 10 hours of my life to figure this out:
1. Open ‘Local security Policy’ by running ‘Secpol.msc’ in the command line.
2. Go to – Local Policies -> Security Options.
3. On the right side scroll down to ‘User Account Control: run all Administrators in admin approval mode’.
4. Change the setting to ‘Disabled’. (YES DISABLED!!!)
5. Restart the server. (Important)
