问题
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

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.

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.

We encountered this error sometimes with MSXML 4, especially when doing installation tests.
Resolution: deinstall and reinstall MSXML.
