Tutorial: Running What You Bought

A step-by-step guide that works even if you've never opened a terminal. About 5 minutes the first time.

What you get after purchase

Right after payment, you land on a success page with a big Download ZIP button. Click it once to save the file to your computer. Each download link is one-time only, so save the file somewhere safe (your Desktop works fine).

Inside the ZIP you'll find:

1Install Node.js (one time, free)

Our apps need a small, free piece of software called Node.js to run. You install it once and then every future app we sell just works.

If you already have Node.js installed (you'll know because you've used it before), skip this step.
  1. Go to nodejs.org
  2. Click the big LTS button on the left
  3. Open the downloaded installer and click through the defaults
  4. Restart your computer if the installer asks you to

2Unzip the file you downloaded

Windows

  1. Find the downloaded ZIP (usually in your Downloads folder)
  2. Right-click it → Extract All...
  3. Click Extract — a new folder appears

Mac

  1. Double-click the ZIP in Finder — it unzips instantly next to the ZIP file

3Double-click the launcher

Windows

Open the unzipped folder and double-click start.bat. A black command window opens. Leave it open while you use the app.

Windows may warn about running a script. Click More info → Run anyway. This happens because the file isn't from the Microsoft Store.

Mac

Open the unzipped folder and double-click start.command.

Mac may say "can't be opened because it's from an unidentified developer." The first time, right-click the file (hold Control + click), choose Open, and click Open in the warning. After that, double-click works normally.

A Terminal window opens. Leave it open while you use the app. After about 3 seconds, your web browser opens automatically to the app's page. If for some reason the browser doesn't open, it's fine — just open your browser manually and go to the URL the app's README shows (usually http://localhost:8080/ or http://localhost:3100/).

4Use the app

Your browser is now showing the app. Use it like any normal webpage. Each product has a short README inside the folder with tips for that specific app.

The black / Terminal window that's open? That's the engine that makes the app work. Keep it open as long as you're using the app.

5How to stop it

When you're done, just close the black command window (Windows) or close the Terminal window (Mac). The app stops immediately.

Next time you want to use it, double-click the launcher again. Fast.

Troubleshooting

"Node.js is not installed on this computer"

Go back to step 1 and install Node.js. After installing, close any open command windows and double-click the launcher again.

Mac says "can't be opened because it's from an unidentified developer"

Right-click (or Control-click) the start.command file, choose Open, then click Open in the warning dialog. You'll only see this the first time.

My browser didn't open automatically

Open your browser manually and go to the URL listed in the app's README.md. For Audio Listener: http://localhost:8080/audio-listener.html. For Claude Voice: http://localhost:3100/.

"Port already in use" / "EADDRINUSE" error

That means you already have the app running (or another app is using the same port). Find and close the other black/Terminal window and try again.

Microphone doesn't work in the browser

FAQ

Can I install this on multiple computers?

The license is for personal use — your own laptop + desktop is fine. Sharing or reselling is not permitted.

Can I download the file again if I lose it?

Each download link is one-time. Save it somewhere safe after you download. If you truly lose it, email admin@silverfamilytree.com with your order number.

Do I need to connect to the internet every time I use it?

Claude Voice runs 100% locally after purchase — no internet needed. Audio Listener's English transcription runs in your browser (offline once loaded). Its Hmong ASR option calls a remote server, so it needs internet.

Can I modify the code?

For personal customization on your own machine, yes. You bought the source files. You can't redistribute or resell the modified version.

What if a new version comes out?

New versions are separate products. You won't automatically get updates.
