2012 SP2 wants to upgrade 2012 SP1 in 2011 SP5 directory

IM defaults to my 2011 SP5 dir for upgrading.  Is there a command-line option to force directory?

I've even renamed the 2011 SP5 dir and it still wants to upgrade the original 2011 directory.  This is regardless of starting upgrade in/outside of SolidWorks 2012.
