[windev] UAC and file ownership problem...

The only solution that I know to the common RW files scenario that works in
all situations (XP/Vista, environments,...) is to modify the files
permissions while you're an admin (in the installer) to grant
everyone/Authenticated Users/whatever the necessary rights.

Note that UAC is not responsible for preventing non-admins to modify the
files. As you noticed, the 'problem' is that by default, Vista doesn't grant
write access to everyone in the ALLUSERSPROFILE.

HTH,

Serge.
