I recently purchased CS3 and installed it on my laptop, seemingly no problem. Want to put it on my other computer as I understand you can have two installs but can only use one at a time. I am fine with that. When I click on the Help menu, there is no deactivate option provided. Also, when I registered the software, went to Adobe to check to see if it showed up, and it didn't indicate that it was registered. Could this be what is happening?
This was purchased from a private party on Ebay. Could this be one component of a suite, where the owner decided they didn't need photoshop so decided to sell it. Could the registration of one of the other elements of the suite invalidate my ability to register it or process the activate/de-activate options.
