Re: ASP.NET Samples Program Error (80040154)

This problem could be caused by not registering/installing the DLL correctly or if permissions are not configured properly to allow the user running the ASP.net application access to the DLL.
You need to uninstall the old COM object using regsvr32:
regsvr32 -u <dllName>.dll
