What prompts message 'photoshop elements 9 cannot start or continue because of missing files, reinstall. When attempt reinstall I have to deactivate my current software. Will this mean I have to forefit the ability to put the software onto a laptop.
While uninstalling you need to deactivate the app. But you have the serial number, right? You can re-activate it after installing.
This time after uninstalling the app, while installing, right click the 'setup.exe' and click on 'Run as admin' and follow the installation process.
