Collaborator client/Visual Studio addin and admin rights

Hi,

We are using Collaborator 10.0 and Visual Studio addin with VS 2015. For some reason we are experiencing problems using the client GUI and VS addin if we don't run them with administrator rights. Without admin rights, the client GUI starts but the Add Changes/Shelvesets/Changesets buttons don't do anything. In Visual Studio, the Collaborator pane shows up but doesn't show any reviews and the Add files to review and New review from changes buttons are dead. When we start the client or Visual Studio as administrator, we have no problems.

Is it a feature that admin rights are required or should they work also without them? Any advice to fix this would be nice.

Thanks a lot,
