Troubleshooting
pdf2zh not found

- Check the Output panel for detailed error messages
- Restart VSCode and try again
- Manual installation: Run
PDF Translate: Setup Environment from Command Palette
- Set custom path in settings:
{ "pdfTranslate.pdf2zhPath": "C:\\Users\\Name\\.local\\bin\\pdf2zh.exe" }
Google Translate fails
Use Bing instead (works without proxy):
{ "pdfTranslate.translationService": "bing" }
