Installing

Download the latest release and run NexStrap.exe.

You will need .NET 9 Desktop Runtime. If it's not installed, Windows will prompt you automatically.

Windows SmartScreen may show a warning on first launch. Click More info → Run anyway. This happens because NexStrap is not yet code-signed.
