Hi Dave,

Check your setting for the screensavers path.

Here are some examples:

Marine Aquarium 2.scr rename it to MarineAquarium2.scr

In the registry, screensaver will work correctly if it is listed as so:
c:\windows\system32\marine~1.scr

Screen Savers do not work correctly if listed as so:
""c:\windows\system32\marine aquarium 2.scr""

How do I get a new screensaver to run? I've run an
installation program and have the *.scr file in the
windows/system32 folder, but the file does not appear in
the drop down box in Control Panel/display/sreensavers.
I then thried to overwrite an existing scr file with the
new one but it won't permit this. If i click on the new
scr file in explorer it runs, I just cannot select in in
Control panel
