Medicat Installer

Old readmes (batch era):

Visit the Medicat website

The Windows installer is now a native C++ app (MedicatInstaller.exe). Same job as before: Ventoy, optional format, extract MediCat, verify files. Linux still has the shell script on the linux branch.

We appreciate some code improvements to the installer!

Requirements for Windows

• Windows 10/11 (1703+ is fine)
• Administrator (UAC)
• Half a brain
• A USB (or VHD) with about 30 GiB+ free, ideally 64GB+
• MediCat.USB.v21.12.7z beside the exe, or grab it from the built-in mirrors / Drive parts

Requirements for Linux

• Like 75% of a brain
• General Linux knowledge
• Script lives on linux and is attached to each release

GitHub Releases

File	Platform
MedicatInstaller.exe	Windows x64
MedicatInstaller-x86.exe	Windows 32-bit
Medicat_Installer.sh	Linux

What it does (short version)

• Installs or updates Ventoy
• Optional NTFS format when you need a clean stick
• Extracts MediCat with progress
• MD5 verify + selective re-extract if something failed
• GUI (dark theme) and a proper CLI (/help, /install, /verify, ...)

More detail: FEATURES.md · CLI.md · UPDATER.md

Quick start

1. Download the exe from Releases.
2. Drop MediCat.USB.v21.12.7z next to it (or use the in-app download).
3. Run as Administrator.
4. Pick your USB. Install. Drink water.

MedicatInstaller.exe /help
MedicatInstaller.exe /install /drive:E /yes
MedicatInstaller.exe /verify /drive:E /yes

Logs land beside the exe as medicat_installer.log. If something blows up and you upload logs, the dialog gives you a Diag code for Discord.

Branches (for nerds)

Branch	What
main	Active C++ installer (you are here)
linux	Shell installer
legacy / legacy-archive	Old batch scripts, frozen
archive/main-cpp-rewrite	Backup of the short rewrite-era main

Batch history is also on tag 3520.

Build from source

Visual Studio 2022+, CMake, Python 3, plus bin/7z/.../7za.exe and MedicatFiles.md5. The build fetches official aria2c (GPL-2.0) and embeds it for multi-connection downloads.

rebuild.bat

Outputs land in build/Release/. Tagged releases (1.0.N) are built on GitHub Actions; see UPDATER.md. Ask in Discord if you get stuck.
