Corrupt Flash Player Error 1722

email me

(1) Use the Adobe Flash uninstaller to remove Flash Player
here

 

(2) Delete Flash Player files and folders

C:\Windows\SysWOW64\Macromed\Flash
%appdata%\Adobe\Flash Player
%appdata%\Macromedia\Flash Player

 

(3) Launch Regedit, delete keys from

HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer\SafeVersions\

 

Or, run script I found on a forum (save as a batch file, i.e. script.cmd):

@echo off
