Hello everyone,

I try to compile a UDF for a 2D case. Unfortunately I encounter a warning which says

Error at host: Error code: 193
Error at Node 0: Error code: 193

My Fluent is Version 19.4.0 for ANSYS 2019 R2.
As far as I know I have to run Ansys via Cross Tools Command Prompt. Thus I installed Visual Studio Community 2019 and Desktop Development for C++.
I run x64_x86 Cross Tools Command Prompt for 2019 as admin. Then I type
C:\Program Files\ANSYS Inc\ANSYS Student\v194\Framework\bin\Win64>RunWB2.exe
This is the Fluent terminal output after building UDF:

Done.

And finally this is what I get after I push the Load button:

DESKTOP-Q4P9KJI: Opening library "C:\Users\tosh\Desktop\linearmotion\motion_files\d p0\FLU\Fluent\libudf"...

I tried to add environmental variables according to https://sites.psu.edu/zfzhang/notes/...f-environment/.

I added these lines to the Path in User Variables:
C:\Program Files\ANSYS Inc\ANSYS Student\v194\fluent
C:\Program Files\ANSYS Inc\ANSYS Student\v194\fluent\ntbin\win64\fluent.exe

Also these for User Variables

INCLUDE
C:\Program Files\Microsoft SDKs\Windows\v7.1\Include
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.23.28105\in clude

Do you have any idea?

I also had problems with Visual Studio 2019. I tried Visual Studio 2015 Express and it worked.
