Default settings of Windows 8 won’t allow you to do install Windows Store not signed apps. If you have an app and want to deploy it for testing purpose, there is a method called development sideloading. A policy or registry key needs to be set to allow trusted apps to run. Here is how you can change the setting.

1. Login in Windows 8 desktop using administrator access rights.

2. Launch ‘Run’ dialog box using Windows Key + R combo or Right-click on Start button and choose “Run” from context menu.

3. In the Run box, type REGEDIT and hit enter.
