Install System-Wide Flash, 32-bit or 64-bit, Uninstall and Deletion Methods as well.
A better looking updated to include 64-bit and 32-bit Flash Installer, making it an easy install, and an almost painless uninstall that requires a little bit of manual changes due to Windows Inheritance :/, If you can delete the 32-bit one without doing the deletion steps in the photo uninstall guide, then I successfully got that one to stop locking as I can delete the 32-bit one every time now.
Hope it works well, don't forget to leave a like/thanks or comment if it doesn't.
