I've been struggling for a week trying to solve a compilation problem. The problem was due to incorrect VS installation. I am a little resentful about the fact that such meager information is designated to this topic (even in Fluent guidelines), hence I decided to make this thread, share my solution and some thoughs.

1. Download VS installer. I use 2019 version, but I am pretty sure it works for the latest 2022 version as well (at least udf.bat script is looking for 2022 build instruments). And of course it should work for previous VS versions.
2. In the installer under Workloads page choose Desktop development with C++ and Universal Windows platform development. This is important. My whole headache was because of this.

3. Launch Fluent via command prompt for VS.
3.1 Find Developer Command Prompt for VS 2019 in the Start menu or just type in the search bar (it could be named different for your version of VS).

3.2 Navigate to your project directory via cd command.
3.3 Type fluent command.

Some technical discourse: personally I don't understand why there is a reason to launch Fluent via VS command prompt, because when you press Build button in Fluent, it starts udf.bat script which is essentially just doing the same thing for you.


After following these steps my problem was solved. Hope it will help somebody.
