I had to rebuild my system and am trying to re-install my old Photoshop 7.0 upgrade disk. It asked for my eligible original disk, which is my photoshop 5.0 backup disk (lost the original in a flood. I'm getting the error message that the 5.0 disk is not eligible, though I know I've done this before. Is there anyway around this?
All the installer needs is the serial info from PS5 in the registry. I have no clue about the exact formatting and order of the keys for each version since it's been too long ago, but when it's present in the correct branch of HKEY_LOCAL_MACHINE\Software\Adobe the installer never even asks for the disc. So if you can produce the proper data, it will work. You could have doen this easily be exporting the registry keys from your old system, but I guess now it's too late for that...
