    Unable to deactivate CS4 - after installing CS5.5




      Today I installed my new CS5.5 upgrade on my Mac and now I wanted to deactivate and uninstall my old CS4 Suite - but it will not work.

      And yes, I have already checked my firewall - turned it off - but no luck.

      I tried to deactivate in Photoshop, Illustrator and Flash - same problem.


      Can I now uninstall CS4 from my Mac without deactivation?


      Any other idea what the problem could be?


      Thanks for any hint
