I am trying to install SQL Server on a new machine. On my first attempt the install failed due to some SQL background program pieces were installed by the vendor on my computer. I have uninstalled all the SQL Server 2012 information, but continue to get the same error as follows: Installation blocked due to detection of versions of Visual Studio that install SQL Server 2012 client libraries. SQL14 CTP1 is prerelease software and should be installed only on a clean machine.
What additional steps or workarounds can I complete to allow for proper installation?
