Hi,

I'm currently working on an old VS 2010 project recompiled to run on 64 bit machine. Its a windows service deployed via .msi installer. The windows service starts fine but when hitting the code that calls an 32 bit dll (interop.schur.dll) it crashes. The logs shows the error below:

Retrieving the COM class factory for component with CLSID {1EB14A4A-3035-4D53-895D-06A60B9E115C} failed due to the following error: 80040154 Class not registered

part of the deployment process is to call regsvr32 schur.dll.

Kindly help please. Thanks.

    Hello,

    Welcome to Microsoft Q&A!

    Currently, Microsoft Q&A supports the products listed over here: supported topics (more to be added later on).

    Your question about Windows service is not supported yet now. You could ask about this in Windows 10 General forum.

    Thank you.
