Solution:

To fix the problem you will need to edit the
[HKEY_CLASSES_ROOT\TypeLib\{91493440-5A91-11CF-8700-00AA0060263B}\2.b\0\Win32] @="C:\\Program Files\\Microsoft Office 15\\Root\\Office15\\MSPPT.OLB"
and point it to the Office 14/15 directory in regedit. 

The easiest way to do it would be to copy the registry entry for the TypeLib 2.a entry and paste it over the 2.b entry.
