I've put a screen saver in the $OEM$\$$ location and it got coped to C:\Windows OK. If also added the registry keys so it gets used by default. This all works but it now appears twice in the list of screen savers inside the GUI. I've searched the disk and there is only one copy. Both versions can be selected from the GUI and they both appear to work.

Any ideas?

What are the reg keys you add?

The key name is SCRNSAVE.EXE under HKEY_USERS\.Default\Control Panel\Desktop.

If I just drop in the name of the SCR file it works, if I give it the actual path i.e. C:\Windows\foo.SCR it doesn't.

I think it's because of the way windows works.

If you dump a .scr file in the windows directory it's listed in the drop down.

Windows uses just the filename because all screensavers are placed in the windows dir.

if you provide a full path I think it sees this as an extra screen saver.

namely "c:\windows\foo.scr" and "foo.scr" seeing c:\windows\foo.scr as a filename instead of a full path.

also, when u place a registry key, (im guessing u are doing it by .reg file)

make sure u add 2 \\ so that windows will look in the appropriate place

C:\\Windows\\foo.scr
