I have created a C#(.Net framework) API to convert Word to PDF using interop.word.dll. I have installed MS Office 2016 on the server. However, even when no one is logged on the server, I am getting the below exception.

"Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 8000401a The server process could not be started because the configured identity is incorrect. Check the username and password. (Exception from HRESULT: 0x8000401A"

Does anyone have any solution for this?

    Office automation (COM interop) is a desktop feature and not recommend for use on a server.

    Alternatively, please suggest other options for converting Word files to PDF.

    Search NuGet for a Word to PDF .NET Framework library. There are a lot of libraries to choose from. Read the docs and find a solution that fits your needs.
