VSTO 2005 SE addin not loading in Excel 2010 RRS feed

  • Question

  • Hi,

    I'm developing addin for excel 2003/2007/2010 using VSTO 2005 SE.

    Everything was good, until I installed VS 2012  (I think that is the reason, but not sure). After that addin stops loading in 2007/2010 excel, and works only for 2003 excel on my dev machine. The same happened for machine where TFS 2012 Express was installed.

    VSTO_SUPPRESSDISPLAY_ALERTS = 0,VSTO_LOGALERTS = 1, but no erros/log files appear on loading and LoadBehavior in registry is changed from 3 to 2.  In COM add-in dialog box load behavior shows the msg "Not loaded. A runtime error occured during the loading of COM add-in."

    Addin is not listed in "Disabled Items".

    Any help appreciated.
