lost cs serial number, can't use cs 4 upgrade installer
Trying to Install CS 4 (upgrade installer) on a clean install of Snow Leopard. Installer is looking for a prior registered product. I had installed CS 4, years ago, when I had been using CS. No longer have the CS installation in place so the installer can't find it. And I can't seem to locate the original discs for CS. I believe this must go back nearly 8 years, maybe more. What can be done in this case to make the installer install? Thanks.
