How to run DevCheck completely

Browsers are not allowed to scan local Windows commands. After extracting the ZIP, use one of the methods below so the AVAILABLE / NOT FOUND results and versions come directly from your computer.

01
Easiest method

Double-click the launcher

Extract the ZIP, then run run-devcheck.bat. The PowerShell window will scan the complete toolchain and stay open when finished.

Download BAT launcher
02
PowerShell 5.1

Run the main command

powershell -NoProfile -ExecutionPolicy Bypass -File .\devcheck.ps1

The Bypass policy applies only to this process and does not permanently change Windows settings.

03
PowerShell 7

Use pwsh

pwsh -NoProfile -ExecutionPolicy Bypass -File .\devcheck.ps1

Use this method when PowerShell 7 is installed.

04
If blocked

Unblock the file

Unblock-File .\devcheck.ps1

Run this once if Windows marks the downloaded file as coming from the internet.

Correct workflow

  1. Download and extract the entire ZIP to a normal folder. Do not run it from inside the ZIP.
  2. Open the extracted folder in File Explorer.
  3. Run run-devcheck.bat, or open a terminal in that folder.
  4. Wait for every check to finish; large engines may take longer.
  5. Read one result per tool: AVAILABLE or NOT FOUND.

What does it check?

Python, C/C++, Java, .NET, Go, Kotlin, Ruby, Rust, Node.js, npm, TypeScript, Vite, Deno, Bun, R, Julia, SQLite, Haskell, Scala, Clojure, Elixir, Erlang, OCaml, Guile, Bash, PHP, Lua, Tcl, Nim, Crystal, NASM, Blender, Godot, Unity, Visual Studio, Unreal Engine, Android SDK/NDK/ADB, and related engine features.

Tcl anti-hang protection

The Tcl version is checked through a temporary file containing puts [info patchlevel], rather than tclsh --version. This prevents the script from entering the interactive % prompt.

GUI Windows

For the desktop interface, extract the source package and run .\run.ps1 or dotnet run --project .\src\DevCheckGui\DevCheckGui.vbproj.
