Patch Analyzer shows SQL 2014 CTP1 (11.0.9120) as a Service Pack for SQL 2012. I am guessing this is because the version number starts with 11.
If this version number is actually correct (i.e. Microsoft's mistake), is there any way that the Idera patch Build List can be modified to remove or otherwise change this entry so that it isn't offered to SQL 2012 servers?
The build of SQL Admin Toolset may ship with an outdated build list. Try updating the Build List and see if this fixes the problem by clicking the Display Build List link. If you are not sure you have the latest list, click Check for New List. This link downloads the most recent list of releases, service packs, and hotfixes for SQL Server software.
I probably should have specified, but yes, that's the first thing I tried. It shows Nov 22 as the most current build list.
The build list shows CTP1 under SQL 2014, but my 2012 servers still show this as an available update.
Note that the current patch level (SQL 2012 CU6) is also being shown as available.
