We had this issue in case of Office Downgrade, or install of different compontents of office at different versions.
In my experience this can be happened in Excel 2010 (x64 or x86) when higher version of any office components are installed (Skype4Business in example).
We have solved the issue removing this registry key (with all subkeys):
HKEY_CLASSES_ROOT\TypeLib\{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52}\2.8
Leave unchaged 2.5 and 2.6
From admin command prompt
reg delete HKEY_CLASSES_ROOT\TypeLib\{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52}\2.8

Maybe this solution can be helpful for #141
