Although I suspect that in your case, seeing the number of programs you've used, it could be that the archive itself is just corrupt and that's why you get an error.
7z or 7zip has nothing to do with windows, windows does have built in support for basic zip (pkzip) (maybe thats what you're thinking of) but 7z is its own format (http://www.7-zip.org/) , and windows won't support it natively.
anyhow newer versions of winrar and obviously 7-zip should be-able to decompress it, exactly what archive are you trying to extract? maybe re-download the archive and try again since it could be corrupted.
