Commented Unassigned: Retrieving the COM class factory failed [21664]

On one machine with win 8.1, office 2013 got an exception (others with the same components are ok)
What could be causing this?

```
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80080005.

Comments: I need to see some caller code. What you try to do? I need to know this to reproduce the scenario. The id :{00024500-0000-0000-C000-000000000046} is the point of interest here. NetOffice failed to find a wrapper class for a COM type with this interface id. I need to know what is this (awaiting) type to clearify the situation. *Sebastian
