I got this application that usally runs on Win server 2000/2003. As a step in
the installation I need to set full control to user gorup 'everyone' in file
system security. XP do not have the same security tab as server version do.

I tried to create the user 'everyone', but that user already exist but do
not show.

Is there som way around this problem. Is it possible to define access to a
user in i.e. registry?
