Install Windows 8 Apps without the Store
These steps will work for Windows 8 and Windows 8.1.
1. Search for “Run” from the Windows Start screen and click on it to open its command prompt.
open-run-prompt
2. Type in “gpedit.msc” and click “OK.”
open-local-group-policy-editor
3. From the main screen of the Local Group Policy Editor, you want to head to the following entry:
Computer Configuration -> Administrative Templates -> Windows Component -> App Package Deployment
4. Double-click on “Allow all trusted apps to install.” -> Enable -> Apply ->OK
6. you’ll want to use Windows PowerShell to run the following command:
add-appxpackage C:\app1.appx –DependencyPath C:\winjs.appx
“app1.appx” is the app you want to install, you’ll need to change this as necessary depending on how it’s named.
“winjs.appx” is the dependency for the app, which you’ll also need to change if necessary. The dependency will be included with the app.
Now, you’re ready to use your new non-Windows Store app on Windows 8.
