I had several versions of Java on my PC and I lamented the fact that I needed to use “Add/Remove Programs” to remove them. This script came in handy although my copy and paste of the code needed several fixups before it would work. The single and double quotes from the copy were funky according to DOS. So I have posted my cleaned up copy. The SyntaxHighlighter Plus plugin has solved this copy problem for me in the past. Good Luck!
