COM class factory error

Question

I've been testing an application using my machine as a server, and everything's going fine with it, but when I try to set it up to run on the test server, I get this error:

Retrieving the COM class factory for component with CLSID {XXXX} failed due to the following error: 80040154.

Any ideas?

Thanks

Answer 1

First: Please check on your test server the registration of your com objects.

HKEY_CLASSES_ROOT\CLSID\{xxxx}

Check, if your dll or exe file is on the correct location on the hard drive.

Answer 2

The error code translates to "class not registered".

Registering is usually done with "regsvr32 " when it is a DLL or via " /RegServer".

To avoid the described error message, please register on client and server.

Answer 3

We encountered this error sometimes with MSXML 4, especially when doing installation tests.

Resolution: deinstall and reinstall MSXML.
