.NET compiled executable

[CasThebe]

I have this .NET application which has to be run as administrator once. The developer says it is only reading from the registry and not much else.
We have a citrix farm based on a provisioning server with a golden image. The farm is refreshed every fortnight. This causes the applocation to fail. After running it as a admin it will work again under a high security user. I would like to have some tips how to figure out what it is actually doing the first run and how to work around it.
