CS3 was released ten years ago, when 64-bit Windows was rarity (if at all available). Try to find a more "compatible" OS where to tri this old version (32-bit Windows XP, 32-bit Windows Vista), or upgrade to more recent one.
Compatability did not work. I don't have the option to try a different OS and I would like to keep Windows 10. I can subscribe to the new Adobe programs as a last resort. Yes it is a legit CS. Thanks for your time thus far
None of the CS3 products are compatible with Windows 10 (or 8 for that matter). Some people have gotten it to run, with bumps along the way, but, it either runs or it doesn't. If it doesn't run on your equipment there is little to no chance of getting it to run. That suite is long abandoned by Adobe and you won't get any assistance from them.
