hello
I've VSTO SE Addin for Outlook 2007.When I install addin setup on one
machine it gives me error "The form region cannot be opened.The form region
manifest specifies an add-in that is not installed". In COM Addins dlg in
outlook , addin is described as unloaded ( in registry LoadBehavior is
3).Form region entries are present in registry.
This error doesn't appear on other 2 machines when I install same setup
there ,addin works correctly ,form regions are also shown.What might be the
reason behind this?

thanks
