#7560 CUDA GPU acceleration unavailable. Verify NVIDIA GPU & CUDA installation (Help -> CUDA Help).

CUDA acceleration requires three things to all be true at once: an NVIDIA GPU, CUDA Toolkit 12.8+, and cuDNN 9.11+.

If any one is missing or the driver is outdated, the software will report unavailable.

1. Confirm GPU is NVIDIA.
   
   AMD/Intel (including integrated graphics) do not support CUDA at all.
2. Run nvcc -V in CMD.
   
   It must report version 12.8 or higher.
   
   If not found, CUDA Toolkit is not installed or not in PATH.
3. Run nvidia-smi.
   
   Update the NVIDIA driver to the latest version if the reported CUDA version is lower than 12.8.
4. Install cuDNN 9.11+ and add its bin and lib directories to the system Path environment variable.
5. Make sure the environment variable Path contains CUDA's bin and lib folders, then restart the software.
6. Note: your install path D:/Installation/dubbing software contains a space.
   
   Move the software to a simple all-English path with no spaces or special symbols, e.g.
   
   D:/pyVideoTrans, then retry.
