The uninstallation of Flash Player can sometimes be problematic and not as easy as clicking on the uninstall button. The first thing that Windows users should note for instance is that there are two versions of the Flash Player plugin available, one for Internet Explorer, the other for the remaining web browsers such as Firefox, Opera or Google Chrome.
If both Flash player versions are installed, both need to be uninstalled before Flash has been removed from the system. While browsers only integrate one version at a time, it is usually a good idea to remove all versions of Adobe Flash from a system if it is causing issues.
And then there is the Google Chrome web browser, which comes with a native Flash plugin installed and enabled by default, which again needs to be handled differently than the rest.
It can happen that the standard uninstallation of the Adobe Flash Player is not successful. Reasons can be data corruption, hard drive errors or that somehow Flash files have been deleted manually to cause issues with the removal process.
Adobe, for those purposes, has created Adobe Flash Player uninstallers for Windows and Mac. These uninstallers remove all traces of Flash from the operating system.
All programs that are making use of the plugin need to be closed before the uninstaller is started. This includes web browsers, but also other software like RSS readers, email clients or Instant Messengers.
The reason for closing all programs is simple. Some flash plugin files may be in use if they are open, and the uninstaller will refuse to remove them. If that is the case close the programs and run the Flash uninstaller a second time.
Some Windows users may need to restart the operating system before all Flash traces are removed from the system. Instructions for disabling the Flash plugin in Google Chrome can be found by following the link above.
