Trying to get my PSE 12.0 to work on my windows vista - having issues between the download version, which never worked, to the DV version that was just shipped to me. I realized that I needed to uninstall the DV version, then reinstall the download version, to transfer the serial number - but now on the download version, all I get at the registration screen is gray and cogwheel spinning forever. Is there something that I am not doing? And also, if and when I get the install, uninstall, reinstall to work, where do I find the 'help' supposedly on screen where I can deactivate and reactivate the serial number? Thanks
