Bought CS3 Extended a few years ago from a reseller on ebay packaged up and sealed in box with printed info. Has serial number sticker on back of the CD case. Adobe support person says it's not a legit serial number as it starts with "1330", 24 digits, total. Had this installed on my previous computer with Vista. Worked find. November 13' had a new PC built with Windows 7 64 bit. Reinstalled CS3 Extended. Worked fine up until about a month ago. Then PC would not open or aknowledge it was on my system. Tried to uninstall, wouldn't let me so had to find software to remove it and all of the components.Did this. Then try to reinstall again but won't let me reinstall.This is what happens. When I put the disc into the CD driver dialogue box says do I want to allow the following program to make changes to this computer? Dialogue box pops up, Program name-Adobe autoplay 5.1. I click yes. Dialogue box pops up with options. Install Adobe Photoshop CS3
