TecniLauncher checks for updates automatically each time it starts. When a new version is available, it notifies you with a changelog and downloads the update in the background — no manual reinstall needed.

How updates work

On startup, TecniLauncher fetches version information from a remote JSON endpoint and compares it to the currently installed version.
  • If a newer version is found, a notification appears showing the changelog — a summary of what changed in the new release.
  • Critical updates prompt immediate installation and cannot be deferred. These are released when a fix is urgent or the current version has a significant issue.
  • Non-critical updates give you the choice to install now or continue with the current version and update later.

Update process

1

Update detected

TecniLauncher detects a new version on startup and displays the changelog. Click Update to begin.
2

Download

TecniLauncher downloads a .zip package containing the new files. Progress is shown as the download runs (“Downloading update package…”).
3

Extraction

The downloaded package is extracted to a temporary folder (“Extracting files…”).
4

Installation

TecniLauncher prepares the installation (“Preparing installation…”), then closes. A script replaces the old launcher files with the new ones.
5

Restart

TecniLauncher restarts automatically with the updated version installed.

What updates preserve

The update process only replaces TecniLauncher’s application files. Your personal data is never modified:
  • Profiles, settings, and session data are stored in %APPDATA%\.TecniLauncher\Data\ and are untouched by updates.
  • Minecraft game files in %APPDATA%\.TecniLauncher\Global\ are also preserved.
During the update, TecniLauncher closes briefly. This is expected — it restarts automatically once the update files are in place.
Keep TecniLauncher updated to get the latest bug fixes, performance improvements, and new features.
