+- Intel Fortran Essentials 2025.3.0.333
+- Microsoft Visual Studio 2022 Version 17.14.23.
+- MATLAB 2025.2.999 (R2025b)
+- Executables with `_OpenMP` or `_OMP` in the name are built with OpenMP libraries and linked with dynamic libraries.
+   - You will need [this Intel Fortran redistributable package](https://registrationcenter-download.intel.com/akdlm/IRC_NAS/0dc56e76-d2c0-4bb8-9c83-c2ee3952b855/w_ifx_runtime_p_2025.2.1.1001.exe) installed to use these executables if you do not already have Intel Fortran OneAPI 2024 installed. See the installation instructions [here](https://software.intel.com/content/www/us/en/develop/articles/redistributable-libraries-for-intel-c-and-fortran-2022-compilers-for-windows.html).
+
+**The other OpenFAST executables DO NOT require these redistributable libraries to be installed. Instead, they were built with static libraries.**
