I just installed the SP5.0, it still doesn't work, in fact I realized that the problem was general, in each field where you enter a dimension you can't do an operation. Hello depression...
At the time for me, in fact, this is a known problem that has no solution when Office 2013 (or higher?) is installed with an older version of SolidWorks (before 2013).
SPR #: 714468
Summary: Math operations in pop up distance mate dimension box do not solve with office 2013 installed
