I’m evaluating HOOPS ACCESS with a trial license. For this evaluation, I’m using CentOS Stream 10 on WSL and CMake 4.2.0. I’ve followed the instructions at [Set Up Your Environment — HOOPS Access documentation](https://docs.techsoft3d.com/hoops/access/start/setup-environment.html) but I get the following error when I run the example bumper test: ```auto ~/HOOPS_Solve_Access_Mesh_Eval_2.12.1_52f38eb1/build$ ./bin/vdm_exam1 ../src/sam/vdm/exam/bumper.unv [DSYSysNLS][ERROR] Missing or invalid ‘SUPPLANG_V6’ file => Falling back to default locale settings LICENSE ERROR: ierr= 15 SYS_ERROR_LICENSE Failure when checking License Missing valid Tech Soft 3D license for this HOOPS toolkit ``` The license is copied verbatim from [Tech Soft 3D Developer Zone](https://developer.techsoft3d.com/hoops/access/trial) → “View your license” (when signed in) and pasted into `src/sam/hoops_license.h`. The cmake commands are `cmake --preset=Linux .. `in `build` and `cmake --build .` Another comment is that I get warnings related to libraries being not detected, but they are at most warnings. ```auto CMake Warning at CMakeLists.txt:247 (message): - Intel Message Passing Interface (MPI) not detected and will be disabled by default!

Hi, Thank you for reaching out to us. It looks like you followed the expected build process. First, the warnings you noticed are expected, as they are related to third parties we do not provide, and options that are not available in the evaluation. Then, as for the licensing issue: I checked the SAM 2.12.1 evaluation package, and it worked on my side. Can you try copy pasting the entire hoops\_license.h file obtained from TechSoft 3D developer zone by clicking on “C Header”? Sorry for the late answer, Sylvain
