There are three ways how you can get access to the app.

1. Microsoft Store:

The simplest way is to just download it via the Microsoft Store.

2. Sideload:

If you don't want to use the Microsoft Store for getting access to UWPX you can also sideload a pre build app.
For this head over to releases and download the latest UWPX-Installer.exe.
Once downloaded, run it and you are ready to go!

For this to work you first have to enable Sideload app in your Windows settings! Click here for more information about this.

3. Build it by your own

Short version:

  1. Install Visual Studio 2022
  2. Clone the repo with Visual Studio 2022
  3. Build the project for your target platform (e.g. x64)
  4. Install the app on your target system: Here you can find more information about: How to install UWP apps, using the developer mode.

Long version:

An extended guide on how to build UWP with images to guide you through can be found here.
