I tried to apply SP1 to an x64 SQL Server 2012 Developer Edition. The initial checks run without issues, but then the update fails, complaining about not finding a file, apparently when trying to update SQL Server Data Tools.
Since installing SQL Server, I have updated SSDT regularly and have what I think is the latest version, from December 2012. Can that be the reason for the failure, maybe SP1 installer is expecting an older version?
Any suggestions on how I can overcome this and install SP1?
Thanks.
