By default, the silent app for Windows won’t run on network/system administrator accounts, which have SIDs ending in -500 or -512. 

This is because new users are created each time a system administrator logs on to a different PC, which can result in many unwanted users in your Time Doctor account.

If you want activity on system administrator accounts to be tracked, access your Company Settings page via the Settings menu and activate the “Allow app to run on administrator accounts” toggle.
