What OS are you using? - You need a 64-bit OS.

Also, please describe as precisely as possible what you are experiencing. “Nothing” does not tell us much. Missing files , if that is a correct diagnostic, could be the effect of an antivirus software sending to quarantine a false positive. Did you look in the AV logs?
