sharepoint products configuration wizard - Unhandled Exception

I have just installed SharePoint Server 2010 on a Windows 7 machine, and every time i try to confogire it, i get an Unhandled exception. Reproduction steps are as follows -- Install Sharepoint 2010 (Server Farm or standalone instance, i've tried both) -- Run the configuration wizard -- Click Ok to the messageboxs (Warning about installing o开发者_StackOverflown Win 7 machine, and another about the wizard restarting certain services).

and then i get the unhandled exception.

EDIT---- the exception i get is "Version string portion is too short or too long"

and im installing on Windows Server 2008 R2

Any ideas?
