Msingi for Windows
One installer for both 32-bit and 64-bit Windows — it detects which one your computer needs. Windows 10 or later.
Version 1.19.0

Download the installer Portable version
Install if the computer is yours to install on — that version keeps itself up to date. The portable version runs from a flash drive without installing, which suits a shared or borrowed computer, but it cannot update itself: download it again when a new version is out.

Updates take care of themselves
Once installed, Msingi checks for a new version shortly after it opens and every few hours after that, whenever the computer has internet. When one is available it says so and waits for you to press Update now — nothing is downloaded without asking, because that costs money on a phone connection.
Copies installed before version 1.5.1 cannot do this and need updating by hand, once. Check the version at the bottom of the sign-in screen; if it is older, download and run the installer above and it will keep itself current from then on.
Installing on a school with no internet
Download it once anywhere there is a connection — a phone, a cyber café — copy it to a flash drive, and run it on the school computer. Msingi never needs the internet again after that. Updates work the same way, and Msingi checks the signature on an update before it installs anything.
Windows will warn you
The installer is not yet signed with a paid certificate, so Windows shows a blue "Windows protected your PC" screen. Choose More info, then Run anyway. Check the SHA-256 above if you want to be certain the file is the one we published.
