Calibrate menu and toolbar do not work in the German-version of Excel


I am running Excel 2007 German, when I select a model and click on the "Calibrate" icon, the excel solver does not pop up, instead I get an error saying that Solver can't be found.  I can use Excel Solver manually, but NumXL can't.

Also, I checked my Excel version, I am have the latest service pack installed (i.e. SP3 MSO (12.0.6662.5000)). Any Ideas,


  • We investigated the problem, and were able to reproduce the reported issue only on the German-version of excel (2003, 2007, 2010 and 2013 (32/64 bit) .

    The problem is rooted in German version of the Excel Solver itself as it provide a locale-specific macros (e.h German) in addition to the English one, and they re-used an one macro name for German version while still in use by the English-named macros.

    In sum, we isolate the problem, and a fix is underway. A new update is scheduled with this fix soon.
