Install RxRescue.

Prefer a portable ZIP? Download the ZIP instead (no installer; extract and run).

Install steps

1. Click Download. Your browser will start downloading the RxRescue installer.
2. Edge / Chrome download warning. Edge will probably show "this file isn't commonly downloaded. Make sure you trust RxRescue before you open it." This is the browser's heuristic — anything not yet downloaded by thousands of people gets this warning. To keep the file: in the Downloads dropdown at the top right of the browser, find the entry for the installer, click the three-dot menu (⋯) next to it, then click Keep. Edge may ask one more time ("Make sure you trust this download"); click Keep anyway. Chrome's flow is similar (click the dropdown arrow next to the partially-downloaded file → Keep).
3. Run the installer. Once the file is fully saved, click it from the browser's Downloads bar, or open your Downloads folder and double-click the RxRescue installer.
4. SmartScreen "unrecognized app" warning. Windows may say "Microsoft Defender SmartScreen prevented an unrecognized app from starting" when you first run the installer. Click More info, then the Run anyway button that appears. This is expected for our current build (we're working on a code-signing certificate; until then SmartScreen flags every unsigned Windows installer). One-time per machine.
5. Click through the installer. Standard Inno Setup wizard — Next, Install, Finish. Per-user install — no admin password needed. The installer offers a "Create a desktop shortcut" checkbox (off by default). Either way, RxRescue lands in your Start menu. The "Launch RxRescue" checkbox on the finish screen opens the app immediately.
6. Connect to your pharmacy. When the app opens, go to Settings → Sync → Join existing sync, enter your setup code (the one we emailed you after checkout), tap Save.

What to do on first run

• Pair your Bluetooth barcode scanner in Windows Settings → Bluetooth & devices. Most pharmacy scanners (Zebra DS2278-SR, Honeywell, etc.) work as HID keyboard-mode devices. Enable "GS character transmission" on the scanner — it's the FNC1 byte that DSCSA barcodes need.
• Set the active zone if your pharmacy has multiple shelves/rooms. Settings → Zones → Add. Otherwise leave it as "All zones" and scans tag without a zone.
• Try a scan or manual entry. Either scan a real bottle barcode, or use the "Add bottle" button to enter one manually. The dashboard refreshes immediately.

Install steps

1. Open this page on your Android phone or tablet. If you're reading from a desktop, type rxrescue.us/download on the device that's actually getting the app.
2. Tap the Android download button above. Your browser will download the APK. Recommended browser: Chrome or Samsung Internet — Brave puts files in a folder some default file managers don't see.
3. Open the downloaded APK. Find it in your Downloads (Files app → Downloads, or your browser's Downloads list).
4. "Install from unknown sources" prompt. Android will ask whether to allow your browser to install apps. Tap Settings → toggle on Allow from this source → back, then Install. Common one-time grant; not specific to RxRescue.
5. Open RxRescue from your app drawer. Settings → Sync → Join existing sync → enter your setup code (the one we emailed you after checkout) → tap Save.

What to do on first run

• Pair your scanner if you'll use one — Android Bluetooth settings → pair with your HID-mode scanner.
• Camera scanning is opt-in. Settings → Camera scanner → Enable. Adds a "Scan with camera" button on the dashboard. Useful when the Bluetooth scanner is on a different counter.
• Multi-device: install on as many Android devices as you want. Use the same setup code on each (or generate a fresh code from Settings); all devices share one pharmacy under one subscription.
