# 1.1 Installation

****Windows Desktop****

1. Run the PupilMetrics installer (`PupilMetrics_Setup.exe`). PupilMetrics can either be downloaded from our website (newest features always released first on our website: [PupilMetrics Windows](https://cnri.edu/pupilmetrics-windows-version/)

PupilMetrics can also be downloaded from the Microsoft store: [https://apps.microsoft.com/detail/9nl4s313hj8t](https://apps.microsoft.com/detail/9nl4s313hj8t)

2. The installer places the application in `Program Files\PupilMetrics` and creates a desktop shortcut.

3. If using a Dino-Lite iriscope, ensure the ****DNVideoX**** driver is installed before launching (see Section 2.5). This will allow you to use the iriscope microtouch feature built into iriscope.

****Android****

Install from the Google Play Store or load the provided APK.

****iOS****

Install MAC PC version directly from this website: [PupilMetrics MAC OS](https://cnri.edu/pupilmetrics-mac-os/)

MAC users, please note: Because this software is distributed directly from our website (and not through the Mac App Store), macOS may show a security warning during installation. This is completely normal.

Apple includes these warnings as part of its **Gatekeeper** security system to protect users from unknown or unverified applications. Why You’re Seeing a Warning

When you try to open the app for the first time, you may see a message like:

> *“This app can’t be opened because it is from an unidentified developer.”*

This does **not** mean the app is unsafe, it simply means Apple has not reviewed or notarized it through their App Store process.

## How to Open the App (2 Easy Methods)

### **Method 1 — Right-Click Open (Recommended)**

1. Locate the downloaded app file (usually in your **Downloads** folder)
2. **Right-click** (or Control + click) the app
3. Click **Open**
4. A warning will appear again — click **Open** one more time
5. This permanently allows your Mac to trust the app.

### **Method 2 — System Settings Override**

If you already tried opening and got blocked:

1. Open **System Settings**
2. Go to **Privacy & Security**
3. Scroll down to the **Security** section
4. You’ll see a message about the blocked app
5. Click **“Open Anyway”**
6. Confirm when prompted

## 🔐 Important Notes

- This process only needs to be done **once**
- Future launches will open normally
- The app does **not** require disabling system security features
- No special permissions are needed beyond standard macOS behavior

## 💡 Extra Tip (If App Won’t Launch)

If macOS still refuses to open the app:

- Make sure the file is fully downloaded (not partially)
- Try moving the app into your **Applications** folder before opening
- Ensure your macOS version meets the minimum requirements

## 🧠 Why This Happens (Simple Explanation)

Apple restricts apps that:

- Are not from the App Store
- Are not signed with an Apple Developer ID

This is a blanket policy — it applies to **all independent software**, including many trusted tools.

## 👍 Reassurance

Thousands of legitimate Mac apps are distributed this way. These warnings are a standard part of macOS and not an indication of a problem with the software.
