If disabling UAC or mimic disabling UAC on host ( set "User Account Control: Run all administrators in Admin Approval Mode" to "Disabled") is not an option...
If it is an option and you want to know how to get to the "User Account Control: Run all administrators in Admin Approval Mode" setting, here is how to get to it:
- Type "gpedit.msc" in the Windows Start menu search box.
- This will open up the Local Group Policy Editor.
- Go to Computer Configuration
- Windows Settings
- Security Settings
- Local Security Options > User Account Control: Run all administrators in Admin Approval Mode
- Change it to 'Disable'.
