#7846 CUDA GPU acceleration unavailable. Verify NVIDIA GPU & CUDA installation (Help -> CUDA Help).

CUDA acceleration is only enabled when ALL of these conditions are met. Check them one by one:

1. GPU hardware: Only NVIDIA (N卡) is supported. AMD/Intel GPUs cannot use CUDA.
2. CUDA Toolkit: version 12.8 or higher. Verify by opening CMD and running nvcc -V.
3. cuDNN: version 9.11 or higher, with its bin and lib folders added to the system Path environment variable.
4. GPU driver: update to the latest NVIDIA driver. Verify with nvidia-smi (it also shows the max CUDA version your driver supports).
5. Environment variables: ensure CUDA's bin and lib directories are correctly appended to system Path.

Regarding your install path:

• C:/Users/Adel/Downloads/Compressed/win-pyvideotrans-v4.15-1

Issues to fix:

• Do not run the software directly from inside the compressed archive folder (the Compressed folder suggests you may not have fully extracted it, or extracted into a messy location). Extract to a shallow, pure English/number path on a non-system drive, e.g. D:\pyVideoTrans.
• Avoid running under C:\Users\...\Downloads\... if permissions or path issues appear; right-click sp.exe → Run as administrator if needed.
