# Development MSIX installation GitHub Releases ship a sideload ZIP for each architecture (`Tonarink--x64-msix.zip` or `...-ARM64-msix.zip`). The ZIP contains `Install.ps1`, the `.msix`, and the matching certificate. 1. Download the ZIP that matches the computer: `x64` for Intel/AMD PCs, `ARM64` for Windows on Arm. The standard `-msix.zip` build is recommended for most users; `-aot-msix.zip` installs the Native AOT variant, while `-portable.zip` runs without installation. 2. Extract the archive. 3. In the extracted `*_Test` folder, run `Install.ps1`. The script installs the certificate if needed and then installs the package. Only install packages downloaded directly from the `kusutori/Tonarink` GitHub repository. Remove the development certificate from the Local Machine **Trusted People** store when these builds are no longer needed. Future Microsoft Store packages use Microsoft's Store signature and do not require this sideload script.
