Yes, do that. But, uninstall and reboot before reinstalling PSE12. Also, review before the crash - if there was a problem with another program that Windows may still have as a task to resolve. If you uninstalled another PSE program then forget to reboot, that can cause a PSE12 installation to crash. Bytheway, you don't need to uninstall a Photoshop to install another. Two or more Photoshop programs will work on the same operating system.
