How to Troubleshoot Flash Player Installation

When installing the Adobe Flash Player, many people found that the Flash Security Update KB923789 in Windows Update would not install normally. When trying to install the Flash Security Update, users would receive an error saying “You must install a later version of the Macromedia Flash Player.” Yet another security update was released in April 2008, but this one has issues, too. Fixing these problems will typically require that you uninstall and then reinstall the flash player to make it work properly. However, simply uninstalling and reinstall Adobe Flash Player using the Add/Remove Programs utility from the Control Panel will not solve the problem. If you version of Adobe Flash Player is corrupted, the application may not uninstall properly and that will cause any new installations to not work correctly.
