So did you unzip the file ok? If you've tried both versions (there was some problems with the installer earlier, but that's been rectified which is why I suggested you re-downld it.)
OK if nothing works & you're getting system errors then: check your system over with your utilities & defregment it. Then use a Registry Cleaner to clean it up. If you don't have one you can find a link here:
