Cannot load brx

Hi,

I have downloaded BricsCAD version 21.2.03 (X64) and the API V21.2.02.
I've build my application (brx-file) with this API, built with v141 but I am getting "oading failed"
Are they compatible BricsCAD v21.2.03 and API v21.2.02?

Is there a way to investigate why the .brx will not load?
