Error calling COM library in asp.net webservice

Question

I am trying to call a COM component (which lives in component services) through a local web service, but it does not work with the following error:

Class not registered (exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

I created a Windows C # application that does the same thing and calls the COM component every time. I assumed that this is a security issue, so I added everyone to the access permissions for component services, but that does not help. Any suggestions? Could this be a 64-bit issue?

Version: VS2008, .NET 3.5, Windows 7, 64 bit
