6.0 doesnt seem to work on XP with no service pack

I have been unable to install the converter or agent from the 6.0 exe's locally on the machine or from the server. Throws a generic error. but does not leave any install log behind to troubleshoot and nothing helpful in windows event log. Cant not install XP service pack 1,2 or 3 on this system due to software compatibility. I figure I need an older version of the converter that will work with this OS.
