Did you try to remove the files for the programs manually before you tried the Add/Remove way? Post the exact error message please.
You can also try to download and install the programs again, then uninstall them.
They are installed on your local hard drive, right?
If so, download revo uninstaller, and you should be able to remove them. Use the moderate uninstall, and it'll check for registry traces so you can remove them. http://www.revouninstaller.com/
Also, check preferences and find if it is being used by the lan.
