Thank you for the reply.
After I selected the run option, nothing was displayed to the screen by the Unistall program. I however downloaded Flash player again and then ran the uninstall using the Windows uninstall option, which seemed to work.
The reason I tried to uninstall Flash player, was because on at least one web site the videos does not play after a while or start playing in slow motion. After uninstalling the latest version I installed an older version of Flash player from the link http://forums\adobe.com/thread/889580. That seems to have solved the issues.
