One-click installer for the full JTS GO toolkit on Windows 7, 8, 10 and 11.

What you get

  • JTS GO 2.1.0 compiler (jtsc), bytecode VM (jtsvm), and runner (jts)
  • JTS IDE — a dark-theme code editor with Run/Build, an errors panel, and an interactive REPL console
  • Standard library scrolls (json, lists, math, os, random, strings, time)

Install

  1. Download and run JTS-IDE-Setup.exe (2.3 MB)
  2. No admin required — installs to your user folder
  3. Launch JTS IDE from the Start Menu, or run jts hello.jts in any terminal

Built as a native Windows executable (MSVCRT, no UCRT dependency) — no Node.js, no .NET 8, no admin rights. The IDE targets .NET Framework 4.8, which ships with Windows 10/11 and is a small download for Windows 7 SP1.

Update (2026-08-03)

  • Fixed a startup crash: the JTS IDE window icon was an invalid ICO that the Windows image decoder rejected, so the IDE failed to open on every machine. Replaced with a valid PNG-based icon.
  • The installer now detects missing .NET Framework 4.8 and offers to download and install it automatically (needed on Windows 7 and older Windows 10).
  • The IDE now logs any startup error to %LocalAppData%\JTS GO\ide-error.log and shows an error dialog instead of failing silently.
