You might want to try to search the forums for help with your problem. It's been my experience that issues with installation (and this goes for any software you may be installing) have been overcome in one way or another on the forums. The forums are your greatest asset in solving installation and other errors. You need to do some searching and reading and then after exhausting that route try asking questions on the forums.
