ODBC Manager error during SQL 2005 setup

I am upgrading my laptop to VS Beta 2 over the weekend. So after a full clean up I started installing the April CTP of SQL Server 2005. And almost at the fag end of the database server install, I get this strange ODBC error: "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified".

Two install trys later a bit of googling landed me at Feb CTP fails during setup with "setup could not connect to the database for server configuration".

Well that solved it. But the strange thing is that the blog issue is fixed for the next release, but the April CTP still seems to have that problem!!
