Do this. Tools>folder Options. there select the View Tab and uncheck the box for hide known system file types.
Click Okay and get back to that folder. Does that archive show just a .zip file? Now right click on it and with WinRar select the "Extract to <Foldername>" option. That should do it.
If it still gives you the above errors, then the archive was not made correctly or needs special software to extract it properly or even possibly corrupt. Cause that should do it.
