Star Video Downloader Help

Everything most users need after downloading the app: Mac and PC install steps, Pro activation help, Gatekeeper or SmartScreen troubleshooting, and what to send if support needs more detail.

Install on Mac

  1. Download the Mac ZIP from the Mac download page.
  2. Open the ZIP and drag Star Video Downloader into Applications.
  3. Open the app and let it install yt-dlp and ffmpeg if prompted.

If macOS says the app is damaged or cannot be opened

Delete the old downloaded ZIP and app first, then download the latest release again. If Gatekeeper still blocks it, move the app to Applications and use Open Anyway in System Settings > Privacy & Security.

If you are comfortable with Terminal and trust this app, this also removes the quarantine flag:

xattr -dr com.apple.quarantine "/Applications/Youtube downloader.app"

Install on Windows PC

  1. Download the Windows installer from the PC download page.
  2. Run Star.Video.Downloader.Setup.exe.
  3. Open Star Video Downloader from the Start Menu or desktop shortcut.
  4. Use the Tools section to install yt-dlp.exe and ffmpeg.exe.

If Windows SmartScreen warns you

SmartScreen can warn on new desktop builds until enough users have downloaded them. Only continue if the installer came from starvideoapp.com and you trust the app. The PC app runs locally and uses the same Pro license method as the Mac version.

Activate Pro

  1. Buy Pro through Gumroad.
  2. Copy the license key from the email receipt.
  3. Open the app, go to Settings, paste the key, and click Activate.

The Settings or Premium screen shows your Free or Pro status, the last validation result, and a manual validation action. If you are moving to another computer, remove the old local activation first so your activation count stays clean.

If the app says your license key was not found right after purchase

Re-download the latest app build from starvideoapp.com and try again before assuming the key is wrong. Some older builds used an outdated Gumroad product identifier and could reject valid keys even when the purchase email and key were correct.

Send Better Support Details

If a download, activation, conversion, or repair job fails, open Settings and choose Export Support Bundle. That file includes backend health checks, queue state, license status, and recent failures without including your full license key.

Email the exported JSON to support@starvideoapp.com with the URL or file you were working with and a short note about what happened.
