Windows – How to use the Messaging app with an account different from the primary Microsoft account

Log on to the windows with the account that you want the application to be installed on. Not the one that purchased it.

Open windows store go to Settings and select your account

Then click change user to the one that purchased it

Once that's done go to YourApps and you'll see the purchased app listed and click on it to install.

Once your done go back to Your Account and press change user to revert back to the normal account

It turns out Adera uses an XBox in game purchase rather than the Windows 8 Store in game purchase which is a further problem. However it is possible to install an app purchased in the Windows 8 store on multiple accounts on the same computer.

1. Purchase the app from the Windows 8 store on the primary windows account.
2. Install the app on the primary windows account.
3. Switch users to the secondary windows account.
4. Launch the store
5. Move your mouse to the top or bottom right corner of the screen bringing up a menu on the right side.
6. Select "Settings" from the menu
7. Select "Your account" from the settings menu
8. Hit the "Sign out" button
9. Hit the "Sign in" button
10. Authenticate with the Microsoft account which made the purchase in step 1
11. Hit the back button
12. Find the app in the store. The button under the price should now say "Install" instead of "Buy"
13. Hit the "Install" button
14. You may be prompted for the Microsoft account password again

Once complete, I suggest signing out of Windows 8 store under the secondary windows account. If you have multiple secondary accounts, you must complete steps 3-14 for each account.

Thanks, Microsoft! This is clearly a superior process to the old process of a single install for all users on a system.
