Do you have definitely have the same version of the DLL installed in your two environments?

Is MDAC (Microsoft Data Access Components) installed with the same version in the deployment environment as in the dev environment?

Latest version from MS is 2.8, IIRC: http://www.microsoft.com/downloads/details.aspx?FamilyID=6c050fe3-c795-4b7d-b037-185d0506396c&displaylang=en

Do you have binary compatibility set?

Every time you compile a COM component created using VB6, a new GUID is created for the component. GUID's and CLSID's are the ones that identify a COM component from the registry. To avoid this binary compatibility is necessary. Read this MSDN blog for details.

I almost hate to ask this, but is the COM DLL registered on the deployed machine?
