GoToResolve.exe - AppLocker - Publisher

Hi, our company uses AppLocker which is blocking all exe-files outside trusted locations. In the past we could add the opener (GoToAssist.exe/GoToResolve.exe) as trusted based on Publisher so our users could open the file from any location. We noticed that this isn't working anymore, error " Object Identifier does not represent a valid object" when we try to add gotoresolve.exe by Publisher in AppLocker policy. Filehash is no option, because it seems that a new filehash is created everytime we send a supportlink to our users. As temporary solution we added GoToResolve.exe with Path condition, but this is not according our security policy.

So, in short, is there any possibility that we can add gotoresolve again by publisher condition via AppLocker?

Thnx in advance.
