"Configuration of SharePoint Products and Technologies failed" error

I kept getting this error while trying to install WSS v3/Project Server 2007 side by side on a machine running WSSv2/Project Server 2003. in this instance i was trying to install the products without upgrading WSS v2 content dbs, hence i did not run the pre-scan tool prior to installing wssv3. in this case when running the psconfig tool after finishing the isntalltion of wssv3 i kept getting an error that .PostSetupConfigurationTaskException has thrown an exception.

 to workaround it, i uninstalled wssv2, project server 2003, rebooted the machine and tried again, now it all works well.
