DsoFile on Windows 10 Build 1909. Does it work?


I download the 64-bit version DsoFile from here: https://www.codeproject.com/Tips/1118708/Bit-Application-Cannot-Use-DSOfile

I was able to install it, register it. Windows says successful and I checked the registry I saw the key. Even I have no problem with referencing it and finish my coding.

But when I ran the program, I got an error:

System.Runtime.InteropServices.COMException: 'Retrieving the COM class factory for component with CLSID {58968145-CF05-4341-995F-2EE093F6ABA3} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).'

Am I am wondering if Dsofile no longer working for Windows 10?

The coding I am using is Vs2019 c#.

Finally, I figured out the problem. It was my program was using 32-bit AnyCPU. Changed it to x64 then it worked.
