I have been trying to get Project Server 2010 RTM installed on a SharePoint 2010 RTM VM but I have been getting an error when running the SharePoint Configuration Wizard.  The error occurs at step 8 of 11 – Creating Sample Data.

The error is “Failed to Create Sample Data” and when you try and view the Project Server Service in Central Admin you get “Object reference not set to an instance of an object”.

The answer – delete the SharePoint – 80 web site in IIS and then re-run the Configuration Wizard.   This is obviously a problem if you have data on the SharePoint – 80 site so let’s hope Microsoft come up with a better solution asap.
