DOWNLOAD STATUS
Windows installer qualification
There is no public Runrail download yet. The installer has to pass its full lifecycle on real Windows machines before this page offers a file.
What is being tested
The public Runrail Setup.exe download remains closed while install, first launch, update, rollback, and uninstall are tested — in that order, on this PC and on a clean supported Windows system. An installer that works once on a developer machine proves little; the clean-system run is the one that counts.
The released installer will not ask you for a terminal, Git, Node, Python, or WSL. If you ever see instructions like that here, the release is not ready.

Try the synthetic review sample in your browser. It uses made-up invoice details, needs no account, and shows the review steps the Windows app is being qualified for.
When the download opens, this page will name the supported Windows versions, the file size, and the checksum before you fetch anything.
