It may be relevant that this system also has CS5 on it. It was only when I ran an sfc scan to resolve some other issues that this problem started. After the Vista to 7 upgrade, Acrobat ran perfectly with no problems. But because Adobe PS CS6 is the latest version, it would be a little difficult to find Adobe Photoshop CS6 license key through network, even though Adobe CS6 download is not so hard. This way can be used by everyone with network. It is the exVista system that is causing the problem. Way 1: Download Adobe PS CS6 and license key again. I note that for whatever reason this system does not have FlexNet on it at all. It functions properly without any need to eneter a serial number.

I have encountered no problems with the system that was upgraded from XP. Both have recently been upgraded one from XP and one from Vista both to Windows 7. If I choose to re-enter the full 24 digit serial number, I get a green tick telling me that this is a valid number but when activation starts I am again told that the 20 digit number is incorrect. It shows only a 20 digit number as being incorrect. As soon as I opened Acrobat, a message pops up telling me that the serial number is incorrect. I entered the serial number during installation which was accepted.

I Uninstalled the software, did the clean up and reinstalled Acrobat 9. Note that you do not 'deregister' Adobe products. Alternatively, for applications downloaded/installed the serial number will be listed in your 'My Account' under the Adobe ID you used at Adobe's web site. You may need to consult the following link to find your serial number.
How to find your adobe acrobat 9 serial number serial numbers#
My solution of removinng the file in FlexNet only worked for one day and when the computer was resarted the following day, the same problem occured. Serial numbers are on a label placed on the container holding the OSM (CD or DVD) that has the install. Ive recently updated my computer and am trying to re - install Adobe Acrobat 9.
