That's just the registration dialog/screen and registration from within photoshop cs3 no longer works properly.
Registration is optional and not required to use adobe programs.
If you turn off your internet connection, then right click the photoshop cs3 shortcut, click on Run As Administrator, then you should be able to to click on Never Register.
After that hopefully you should be able to run photoshop cs3 normally without getting that dialog/screen.
That's an old adobe registration site for older software like cs3.
It no longer works
The same thing happens on normal perpetual license versions of photoshop cs3 and adobe elements 6 on
both mac and windows.
I don't think it's anything to do with whether its a volume license or not.
Thanks for helping me! I wished live support had your answers instead of making me wait 3 hours to tell me I gotta go to the forums for help.
CS3, 4, 5, 6 are all out of support now.
