Run http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html - that should uninstall all Flash Player versions.
Make sure the following folders are empty before you reinstall:
- C:\Windows\syswow64\Macromed\Flash (if you are on a 64-bit system)
Hi Pat. Thanks for replying. I already tried that uninstaller
previously, but it didn't work in my case. Nevertheless, I tried it
again just now. I also deleted the folders you indicated. Despite this latest attempt, the
Adobe Flash Player 10 Activex entry still appears in my Programs and
Features and still has no uninstall option.
