I am using Mathcad Prime 6.0 6.0.0.0

Dear Support,
I have downloaded the C# WPF project for using the API Mathcad (https://support.ptc.com/help/mathcad/r7.0/en/index.html#page/PTC_Mathcad_Help%2Fexample-2_ms_dev_studio.html%23) but it does not work (Problem to connect Mathcad Prime).
I'm using Prime 6.0.
Is this version compatible with your API ?
Thanks
Regards,
Irénée

Here are the errors that I faced
ex.Message = "Retrieving the COM class factory for component with CLSID {A00E8B95-D415-433F-A04E-D298A54A7BB7} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))."

Thanks for the answer Vladimir.

I tried to change the target platform "x86", "x64", "Any CPU", without success.

The problem occurs when I want to start Mathcad (error during the instanciation "_mathcadPrimeApplication = new Ptc.MathcadPrime.Automation.ApplicationCreator();")
