- Each time you install a new version, you may need to delete the cache of your browser and restart it.
- Before updating JRT, check that your JRT update license doesn't expire before the date indication in orange above the version you are about to download.

NOTE : CUDA is only used for a specific setting of the photo mode and works only with old Nvidia cards. If you don't need it, it's better to install the version without CUDA that is lighter.
