After that, launch the **XReach** app with **RealWear Glasses**. ## Longform In order to update **XReach** to your **RealWear Glasses** device, you will need the following: 1. A charged set of **RealWear Glasses**. Don't try any updates without making sure you have at least 50% battery. 2. **RealWear Explorer**, installed and running on your **PC** or **Mac**. 3. A functioning USB-cable for connecting your **PC** or **Mac** (and therefore **RealWear Explorer**) with your **RealWear Glasses**. 4. The **XReach RealWear .APK file**, which **Softability** or your **IT department** will deliver to you. ### Install RealWear Explorer **RealWear Explorer** is an application for connecting your **RealWear Glasses** with your **PC** or **Mac**. One of the more useful things you can do with this application is to install an app onto your Glasses. Please visit the following link for installing **RealWear Explorer**. From that page, you will click on one of the following links (see screenshot below) ![RealWear Page with clickable Download links](https://4219527844-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MMPaHg7zC9PGFTMjK1L%2F-MOecsjzcuajYJrm_63X%2F-MOeeIxn0sHl05prGhjk%2Fimage.jpeg?alt=media\&token=28ffd0bb-8a74-4b37-8168-e1f7caf59c64) After the download finishes, it's time to run the installer. If you are unsure as to what to do, follow the installation instructions on the RealWear page above.\ \ There, installing finished, now, launch **RealWear Explorer**. ![RealWear Explorer, waiting for you to connect your RealWear device ](https://4219527844-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MMPaHg7zC9PGFTMjK1L%2F-MkAoJhwgODgYua3xQkG%2F-MkAq3QUmumDrcC9mfxu%2FScreenshot%202021-09-22%20at%207.51.22.png?alt=media\&token=78452b17-5251-4004-aea1-9855febd0755) ### Pair RealWear Glasses with RealWear Explorer While **RealWear Explorer** is open, connect your **RealWear Glasses** onto your **PC** or **Mac** using the correct USB cable. **RealWear Explorer** will detect your Glasses and prompt for the installation of the **RealWear Cast** app onto them. ![RealWear Cast app installation prompt](https://4219527844-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MMPaHg7zC9PGFTMjK1L%2F-MOAmXLtesK42pOgGO0T%2F-MOApDnhe2J6tYl7738Y%2Fimage.jpeg?alt=media\&token=27db4cbc-f290-4dee-84d9-892e28bf525b) Click on **Yes** on your Computer. **RealWear Cast** installation will start on your Glasses. Whenever the **RealWear Cast** is launched, and the **RW Explorer** application mirrors your **RealWear Glasses**, there will be a security popup notifying you that anything you show will be seen by whoever is viewing the view from the **RW Explorer** app. Know what this means, and click on **`Start Now`** to continue. You can also say **`Start Now`** to continue. ![Yes, everything will be shown. Say Start Now.](https://4219527844-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MMPaHg7zC9PGFTMjK1L%2F-MkAoJhwgODgYua3xQkG%2F-MkAqE5G3l0pokO-HOTY%2Fscreenshot_1632286306602.png?alt=media\&token=735bf9f6-1d94-41ad-ae99-bd39a5c2052d) Now that the **RealWear Cast** app has started, you are able to control the Glasses and take screenshots, and install APKs using the **RW Explorer** app. ### Using the Dropzone to install XReach At the top right corner of the **RealWear Explorer**, you will see **Drag and Drop APKS Here**. Please check the screenshot below for where the so called Dropzone should be. ![The Dropzone for dragging your APK file to](https://4219527844-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MMPaHg7zC9PGFTMjK1L%2F-MOfBk9Td27xFd9fmkLB%2F-MOfCr7L9JiHl-1XwOWK%2Fimage.jpeg?alt=media\&token=f7a78c86-080f-493d-97e9-3c31e97961ee) Now, navigate to your File Browser (such as Explorer or Finder), locate the **APK** file that has been provided to you by either **Softability** or your **IT department**. Position the File Browser window so that you can see the **Drag and Drop APKS Here** dropzone near it, and click and drag your APK file onto the Dropzone - like this: ![Dragging and dropping an APK to the Dropzone](https://4219527844-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MMPaHg7zC9PGFTMjK1L%2F-MOfBk9Td27xFd9fmkLB%2F-MOfFHE31mA8vZX5HDZv%2Fdrag%20and%20drop.gif?alt=media\&token=f24e8946-d316-498c-819c-4e3b501fdb6f) If you got as far as seeing a dialog that says **Successful install**, please proceed towards launching **XReach**. ### Launching XReach Now, command your **RealWear Glasses** by saying:\ \ **`Navigate Home`**->**`My Programs`**-> **`XReach`** You have now successfully manually updated and launched the **XReach** application on your **RealWear Glasses** by using the **RW Explorer** application. Now would be a great time to check the ["XReach RealWear Voice Commands"](/xreach/realwear/xreach-realwear-voice-commands.md) article.
