I cannot extract any files

[DRK]

Please help! I downloaded 7-Zip in order to download another file, but now I cannot extract any files and every time I attempt to "Uninstall" or remove the 7-Zip file in my control panel, it tells me that it cannot open the file as an archive.
IAny suggestions will be appreciated.

If you open Control Panel then click on Programs and Features, right click on 7-ZIP and select Uninstall, what happens?
If that works, try downloading 7-Zip here: 7-Zip
