The subject line captures what I need to do. I tried entering my activation code on the new Windows 7 computer, but I get the error message Invalid Application Code. I have not yet uninstalled the software from the old computer. Please describe the process I should follow to move the software to my new PC. IWhen I run the uninstall process, will the activation code be released at the Applian server so I can use the same code on the new computer? Or do I have to request a new code? I appreciate your help. Rob
