 ## "Failed to load PyTorch native library" while trying the AI chat
 
-If you encounter this error, download the latest [Visual C++ redistributable from Microsoft](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-microsoft-visual-c-redistributable-version).
+If you encounter this error, download the latest [Visual C++ redistributable from Microsoft](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-microsoft-visual-c-redistributable-version). This installation is only required for AI features in JabRef, all other features can work without it. Also, if multiple installations of CUDA are installed, JabRef's Version needs to be added to the PATH first. For example, on Windows this would be adding `C:\Users\USER\.djl.ai\pytorch\CUDA-VERSION` to the Environment Variables. See [how to edit environment variables on Windows 10 or 11](https://www.howtogeek.com/787217/how-to-edit-environment-variables-on-windows-10-or-11/).
