Domino COM classes are 32-bit only and will fail if recompiled as 64-bit for Windows 7 x64

Technote (troubleshooting)


Problem

When a Domino COM application is recompiled as 64-bit, it fails. Specifically, when attempting to set the Notes session, you will see an error similar to the following:

Error: Retrieving the COM class factory for component with CLSID {29131539-2EED-1069-BF5D-00DD011186B7} failed due to the following error: 80040154


Symptom

Error: Retrieving the COM class factory for component with CLSID {29131539-2EED-1069-BF5D-00DD011186B7} failed due to the following error: 80040154


Cause

The Domino COM classes are not supported on a 64-bit OS. Updating the classes for 64-bit is under consideration but not currently planned.

Resolving the problem

The application that will need to use COM needs to be compiled for 32 bit vs 64 bit
