This is because it requires certain permissions which are only granted if run from a secure location.  Program files is the only secure location accepted by the OS by default.  Making another folder and giving it admin only write access would not produce the same results either.

Quite why the installer is asking that I don't know as given it isn't allowed the installer should be skipping past that page.  I will raise that internally.

Than it is best to work with your it department to allow Groupy to be install in its default directory. As mentioned above Groupy will not work properly if install in not default directory.
