ComException while running Project in VS2019


When running a project with Visual Studio 2019, I always get the following error:

System.Runtime.InteropServices.COMException HResult=0x80040154+ Message = The COM class directory for the component with CLSID {DE88C160-FF2C-11D1-BB6F-00C04FAE22DA} could not be retrieved due to the following error: 80040154 Class not registered (HRESULT exception: 0x80040154 (REGDB_E_CLASSNOTREG)).

I've already tried:

  1. Create key in registry
  2. Visual Studio newly installed
  3. Try 32 bit and 64 bit.
  4. Execute the .exe after creating it from the Explorer. The error remains.

    Running with 64 bit

I noticed that only in this project the error message appears. I have changed my system to Win10. Thanks for every help.
