I can't install Android from the store, do you have another option to install the app?

Your organizer should have provided you with a launch page to the app. Simply access this page from your desktop computer and you will see a URL listed to install the Android app file (.apk) directly on your device.

Enable your device to install files outside the store:

Option 1

1. Open your device's Settings app
2. Scroll to the Security tab and select it
3. Slide Unknown Sources to ON (Allow installation of applications from both trusted and unknown sources)
4. If you are prompted with a security vulnerability warning, tap OK (Follow these steps and turn installing from Unknown Sources OFF after you installed the event app)

Option 2

1. Go to Settings
2. Find the Security & privacy option and tap on it.
3. Scroll down and look for 'install from unknown apps'. If it's not there, try under 'more'.
4. You should be presented with a list of apps. Find your browser - Chrome, for example.
5. Tap on it and then select Allow from this source.

Option 3

1. Go to Settings
2. Go to Apps & notifications and then select configure apps.
3. Scroll down. Find and tap advanced options or special app access.
4. Scroll to the bottom of the special app access menu, where you can find the Install unknown apps option.
5. Find your browser, (e.g. Chrome), tap it and select Allow from this source.

Install from the link:

1. Open the Chrome browser on your device
2. Enter the provided URL. You may be prompted to download the file. Press OK
3. To access the file, either tap the Download Complete from the notification bar (swipe down from the status bar at the top of your screen) or, go to Applications > File Manager (there may be an app called "My Files" or "Downloads" or "Files" depending on your device manufacturer) and find the Download folder
4. Tap the .apk file you downloaded to install and follow the prompts on your device.
