Try going to Start/Programs and scroll to the program and see if the uninstall program for it is listed there and try uninstalling it there. If you can't uninstall it (perhaps because it's considered to be 'in use' by windows), then try this MS uninstaller utility.
Windows Installer Cleanup Utility can be downloaded from the above link and it will remove installed programs that can't be uninstalled from the Add-Remove Programs List because you don't have the cd anymore or because the program itself can't locate its uninstall file info.
There is one version of this utility available for individual windows versions from W95, W98, ME, NT 4.0, 2K, XP, and Server 2003. Direct download can be reached at this link:
What i did was, i went to the control panel and to the part where it says to remove or change programs and tryed to delete it. This didn't work but it should work. My computer freezes every time I try attempting deleting this file. I don't know how to get rid of it, the reason i hate it so much is because whenever i want to download something from the net it never works when i try and open it up with that program, it never unzips either.....HELP ME I NEED IT BIG TIME.....I don't wanna reformat my computer either.
