Here you can see the SID of the Active Directory object that’s authorized to manage App-V, using PowerShell (for instance) you can determine which account a SID belongs to (see Microsoft TechNet), However. the easiest way to regain access is to add your users SID to the table and assign the role “ADMIN”.  The table has the following columns:

That’s it, no restart is needed.
