Ah, this is the problem.. :-) Writing this file makes it virtualized 
into the currently logged-in user's VirtualStore.

That's correct - anything that gets virtualized ends up being 
virtualized for only that user... so until we get a tool that lets our 
apps get elevated permission levels on Vista (hint, hint, RunRev?), we 
cannot install in a universally accessible area to all users without 
having someone with a specific set of permissions log in and do it.
