Which operating system? What computer? what exactly have you tried so far? You need to be more specific....
Using Vista. For the licensing issue I tried all of this:
Solution 8 is to reinstall. But now when I try to reinstall, it won't install any of my programs. It says something along the lines of "Photoshop CS3 Failed to Install" and that's about it.
Prior to trying to reinstall, I did try to uninstall all my Adobe software.
Did this work for you?
I had all of my application in CS3 Web Premium Working. I tried the Cloud and downloaded a number of Apps Photoshop CS6 and Acrobat x. Before I did I asked if It would affect any of the application I currenlty owned. Oh No, you will only need to uninstall the products you downloaded from the cloud and everything would work as it did before. At first all did except Acrobat 8 it told me my licences was not valid. I called support and was told they would not support it. Lied to again.
I have deactivated all of CS3 uninstalled everything at least 3 times used the cleanup tool and now I can't even get the apps to install.
I also have a full version of CS4 Web Premium which I was considering upgrading. Well this is the support I get why should I. Or why should anyone if their products cause the problem and then they will not even assist in fixing it. Moore to follow...
Follow Up and solution....
Use Windows Uninstall > Use Adobe Clean up tool> Manually remove remaining adobe folders under Program files > make sure firewall is turned off during install allowing the installer to get all of the updates during the install. It will then let you activate.... What a pain.
Thank you Adobe Non-Support Team
