How to Install HoloLens Apps and Set Up Your Device

Just unboxed your new HoloLens? Or maybe you’re wondering how to install apps on the device you already own? You’ve come to the right place. I’ve been there, staring at that sleek mixed reality tech, excited but also a bit confused. Getting apps onto your HoloLens doesn’t have to be a headache.

Whether you’re looking to dive into experiences from the Microsoft Store, sideload a specific application, or even deploy your own custom creations, I’m going to walk you through each step. We’ll cover everything from the very first power-on to advanced developer setups. Let’s get your HoloLens ready for action!

Getting Started with Your HoloLens: Initial Device Setup

Before we even think about apps, let’s make sure your HoloLens itself is set up and ready to rock. This initial HoloLens setup is crucial for a smooth experience.

Unboxing and Powering On Your HoloLens

First things first: power up! Locate the power button (usually near the left temple on HoloLens 2). Press and hold it until you see the Microsoft logo appear. You’ll hear a little chime, and the device will boot up. Take a moment to adjust the fit so it’s comfortable and stable on your head.

Performing Initial HoloLens Calibration

Once powered on, the HoloLens will guide you through eye calibration. This step is super important. It ensures that holograms appear correctly aligned with your real-world environment, no matter how much you shift your head. Follow the on-screen prompts, looking at the “gems” as they appear. If you skip this, you’ll likely be prompted again later, and trust me, properly calibrated holograms make a world of difference. It’s like tuning a guitar before playing a concert – essential for the best performance.

Connecting Your HoloLens to a Network (Wi-Fi & Ethernet)

A network connection is a must for almost everything on HoloLens, from initial setup to downloading apps. Your device will prompt you to connect to a Wi-Fi network. Just select your network and enter the password. If you’re using a HoloLens 2, you can also connect via Ethernet using a USB-C-to-Ethernet adapter. Ensure it’s a network you trust, especially for initial setup, as public networks might have security restrictions that complicate things.

Signing In: Microsoft Account vs. Work/School Account

Next, you’ll need to sign in. You’ll have two main choices:

• “I own it” (Microsoft Account): This is for personal use. Simply enter your Microsoft account credentials. If you have two-step verification enabled (which I highly recommend!), complete that process.
• “My work or school owns it” (Microsoft Entra ID/Azure AD account): If your organization provided the HoloLens, use your organizational credentials. This often means the device will automatically enroll in mobile device management (MDM) if your organization has configured it.

Setting Up Iris Sign-in and PIN for Your HoloLens

For convenient and secure access, you can set up Iris sign-in. This uses your unique eye patterns to log you in quickly – it’s a truly sci-fi experience! The setup is similar to eye calibration. You’ll also be prompted to create a device-specific PIN. This is a crucial backup in case Iris recognition isn’t convenient or doesn’t work for some reason.

Installing Apps on HoloLens: Your Options

When it comes to how do I install HoloLens app experiences, you have a few powerful ways to do this, catering to different needs and technical levels.

How Do I Install HoloLens Apps from the Microsoft Store?

The simplest way to get new experiences is through the built-in Microsoft Store.

Accessing the Microsoft Store on HoloLens

Perform the “bloom” gesture (holding your hand up, palm facing you, and bringing your fingertips together) to open the Start Menu. Look for the “Microsoft Store” tile (it’s usually a shopping bag icon). Gaze at it and perform an air-tap gesture to launch the app.

Searching and Downloading Apps

Once in the Store, you can use the virtual keyboard to search for specific apps, or browse categories. When you find an app you like, select “Get” or “Install.” The app will download and install automatically, just like on a PC or smartphone. Make sure to accept any permissions requests (like camera or microphone access) if prompted – they’re often necessary for the app to function correctly.

How Do I Install HoloLens Apps Using the App Installer (Sideloading Made Easy)?

For many users, especially those not deeply involved in development, the App Installer is a game-changer for sideloading applications (installing apps not from the Store). This feature, introduced in Windows Holographic version 20H2, allows you to install .appxbundle files much more easily.

Understanding App Installer Prerequisites (Unmanaged Devices)

The App Installer works best for “unmanaged” devices. If your HoloLens is enrolled in MDM, configured with a provisioning package, or uses a Microsoft Entra ID user identity, it’s considered “managed,” and this method might be restricted. For personal devices, it’s usually on by default.

Transferring App Packages (.appxbundle) via USB

One common way to use App Installer is by transferring the app package directly. Connect your HoloLens to your PC via a USB-C cable. Your HoloLens should appear as a drive in File Explorer (e.g., This PC > HoloLens).

Navigate to Internal Storage > Downloads your HoloLens. Copy your .appxbundle file from your PC to the Downloads folder. Once copied, you can disconnect your HoloLens.

Installing Apps Directly from File Explorer

On your HoloLens:

• Open the Start Menu (bloom gesture).
• Select “All apps” and launch the “File Explorer” app.
• Navigate to the “Downloads” folder (you might need to select “This device” first on the left panel).
• Gaze at and air-tap your .appxbundle file. The App Installer will launch automatically.
• Select the “Install” button within the App Installer. The app will install and often launch automatically upon completion. It’s incredibly straightforward!

Web Install for HoloLens Apps: Setting Up and Using

You can also install apps directly from a web server!

• For the App Provider: The app needs to be correctly configured for web installation, and you’ll typically host the .appxbundle file on a web server with an associated XML manifest. You’ll also need to ensure the app’s digital certificate is trusted by the HoloLens devices.
• For the User: Once the certificate is trusted on your HoloLens (either pushed via MDM, a provisioning package, or manually installed), you simply visit the provided URL in Microsoft Edge on your HoloLens. The App Installer will recognize the file and prompt you to install. This is fantastically convenient for distributing apps to a larger group without needing physical access to each device.

How Do I Install HoloLens Apps Using Windows Device Portal (Advanced Sideloading)?

The Windows Device Portal is a powerful web-based tool that gives you much more control over your HoloLens, including advanced app deployment. This is especially useful for developers or for sideloading apps when App Installer isn’t an option.

Enabling Developer Features on Your HoloLens

Before using the Device Portal, you need to enable developer features on your HoloLens:

• Perform the bloom gesture to open the Start Menu.
• Select the “Settings” tile.
• Navigate to Update & Security > For developers.
• Toggle “Use developer features” to On.
• Scroll down and enable “Device Portal.”

Connecting to Windows Device Portal (Wi-Fi & USB)

You can connect to the Device Portal via Wi-Fi or USB.

• Over Wi-Fi: Ensure your HoloLens and PC are on the same network. On your HoloLens, go to Settings > Network & Internet > Wi-Fi > Advanced Options to find your device’s IP address. Then, from a web browser on your PC, go to https://<YOUR_HOLOLENS_IP_ADDRESS>.
• Over USB: Connect your HoloLens to your PC with a USB-C cable. If you have the Windows 10 SDK with IPOverUSB installed, you can typically access it by going to http://127.0.0.1:10080 in your PC’s browser.

Addressing Security Certificate Warnings

The first time you connect, your browser will likely show a “security certificate” warning. This is because your HoloLens generates a unique self-signed certificate that your PC doesn’t automatically trust. You can usually bypass this by clicking “Continue to this website” or a similar option. For more secure, persistent access, you can download the certificate from the Device Portal’s Security page and install it in your PC’s “Trusted Root Certification Authorities” store. I recall the first time I set this up, it felt a bit like navigating a digital maze, but once you do it, it clicks into place.

Creating a Device Portal Username and Password

The very first time you connect to the Device Portal, you’ll be prompted to create a username and password.

• Click “Request pin” on the webpage.
• A PIN will appear on your HoloLens display. Enter this PIN into the “PIN displayed on your device” textbox on your PC.
• Choose a username and a password (at least seven characters). This does NOT need to be a Microsoft Account credentials.
• Click “Pair” to establish the connection.

Deploying .appx or .appxbundle Files Through Device Portal

With the Device Portal connected:

• In the left navigation menu, go to View > Apps.
• Under “Deploy apps,” click “Choose File” and browse to your .appx or .appxbundle file.
• If your app has dependencies (like Unreal Engine apps sometimes do), select “Allow me to select optional packages” and upload the dependency .appx file as well.
• Click “Install.” You’ll see a progress bar, and once complete, your app should be ready on the HoloLens!

Setting Up Your HoloLens for Custom App Development

If you’re looking to create your own mixed reality experiences, setting up your HoloLens for custom app development involves preparing both your device and your development machine.

Essential Software for HoloLens Development (Visual Studio, Unity)

You’ll typically need:

• Visual Studio: The professional IDE from Microsoft. Make sure to include the “Universal Windows Platform development” and “Game development with Unity” (if using Unity) workloads, along with the Windows 10 SDK.
• Unity (or Unreal Engine): These are popular engines for building mixed reality content. Ensure you install the necessary modules for Universal Windows Platform (UWP) support.
• HoloLens 2 Emulator: If you want to develop and test without a physical device.

Configuring Your PC and HoloLens for Deployment

Once your development environment is set up, you’ll often deploy directly from Visual Studio. This usually requires your HoloLens to have Developer Features enabled (as discussed in Section II.C.1) and to be connected to your PC via USB or on the same Wi-Fi network. Visual Studio handles the deployment process, compiling your project into an .appxbundle and pushing it to the device.

Understanding App Packaging and Digital Signing for HoloLens Apps

When you build a custom app, Visual Studio creates an .appxbundle package. For your app to run on a HoloLens, it must be digitally signed.

• For development, Visual Studio often uses a test certificate.
• For broader distribution or enterprise use, you’ll need a certificate from a trusted Certificate Authority (CA) or a self-signed certificate that is then pushed to the HoloLens devices. This signing process confirms the app’s authenticity and integrity, a critical security measure.

Troubleshooting Common HoloLens App Installation Issues

Encountering problems when you install HoloLens app packages can be frustrating, so here’s how to diagnose and fix common issues.

App Not Appearing After Installation

It’s frustrating when an app seems to install, but then you can’t find it.

• Check “All Apps”: After installation, always check the “All apps” list in your Start Menu. New apps might not automatically pin to your main Start screen.
• Reboot HoloLens: A simple restart can often resolve minor display glitches or indexing issues.
• Verify Installation in Device Portal: If you used the Device Portal, check the “Apps” page. It will list all installed applications. If it’s not there, the installation likely failed silently.

Installation Failures and Error Messages

If you get a direct error message during installation:

• Network Connectivity: Ensure your HoloLens has a stable internet connection if downloading from the Store or using web install.
• App Package Integrity: Make sure the .appx or .appxbundle file isn’t corrupted. Try re-downloading it.
• Device Space: Check if your HoloLens has enough free storage.
• Dependencies: For complex apps, ensure all required dependency packages (.appx files) were also installed. This is common with game engines like Unreal Engine.
• System Updates: Sometimes, apps require a specific Windows Holographic OS version. Ensure your HoloLens is up to date via Settings > Update & Security > Windows Update.

Let me give you a quick hypothetical: Imagine you’ve downloaded a custom .appxbundle from a shared drive, tried to install it via App Installer, and it failed with a generic “Installation Failed” message. My first thought in this scenario is always, “Is this app correctly signed, and does my HoloLens trust the signer?” That’s where you’d check the certificate trust.

Certificate Trust Issues for Custom Apps

This is a big one for developers. If your custom app isn’t signed by a trusted certificate, the HoloLens will refuse to install it.

• Self-Signed Certificates: If you used a self-signed certificate, you must push that certificate to your HoloLens first. This can be done via a provisioning package, MDM, or manually through the device’s Certificate Manager.
• Developer Mode: Ensure developer features are fully enabled, as some security checks are relaxed (for test purposes) in this mode.

Connectivity Problems with Windows Device Portal

If you can’t even connect to the Device Portal:

• IP Address: Double-check the HoloLens’s IP address.
• Network Connection: Confirm both your PC and HoloLens are on the same network and that no firewall rules are blocking the connection.
• Developer Mode/Device Portal Enabled: Make sure both settings are still enabled on your HoloLens. Sometimes, they can get toggled off accidentally.
• Browser Issues: Try a different web browser on your PC, or clear your browser’s cache.

Managing and Updating HoloLens Applications

To ensure optimal performance and security, it’s essential to keep your HoloLens apps and operating system up-to-date.

Checking for App Updates on HoloLens

Apps installed from the Microsoft Store will generally update automatically when connected to the internet. You can manually check for updates within the Microsoft Store app itself by navigating to your Library or Downloads. For sideloaded or custom apps, you’ll typically need to re-deploy a newer .appxbundle using the App Installer or Windows Device Portal.

Best Practices for HoloLens Device and App Maintenance

• Regular Updates: Keep your HoloLens OS updated (Settings > Update & Security > Windows Update). OS updates often include performance improvements, bug fixes, and new features that apps might rely on.
• Storage Management: Periodically check your device’s storage (Settings > System > Storage). Uninstall apps you no longer use to free up space.
• Reboot Regularly: Just like any computer, a regular restart can clear out temporary files and refresh the system, leading to better performance.
• Secure Network Use: When sideloading or accessing the Device Portal, always ensure you’re on a secure and trusted network to prevent any data interception.
