Well, I’m in the process of configuring a new Vista Ultimate system on an Intel 64-bit cpu.
One of the first problems I had was I wanted to get the google screensaver working. I downloaded Picassa and that includes the screensaver app, but I was not seeing it as an option on my windows control panel screensaver section!
Turns out you need to:
Go to C:\Windows\SysWOW64 folder, copy the file
GPhoto.scr and paste it in to the C:\Windows\System32 folder.
Now it works great! Now if only google will adapt it to allow arrow controls to go back/forward through the photos.
One more note… if you using windows media player to play music, you’ll need to go into tools->options and check the “allow screensaver during playback” box to have the screensaver work when music is playing.
