Launcher Executable Compatibility (.exe, .bat, .cmd), Hidden Environment Access Key Fix, Installation Path Fix, Previous Install Location Detection

---

Desktop Launcher

Executable Format Support: .exe, .bat, .cmd

NEW FEATURE: The desktop launcher now supports launching .exe, .bat, and .cmd executables. Configurable directly from the Dashboard!

NEW - App Platform Settings - Executable extension dropdown

Game executables are no longer limited to .exe files. You can now configure .bat and .cmd files as your game's primary or secondary executable in the Dashboard, and the desktop launcher will handle them correctly.

Supported formats:

Format	Description
.exe	Standard Windows executable
.bat	Windows batch script
.cmd	Windows command script

Possible Previous Install Locations

NEW FEATURE: The launcher now searches known locations to automatically detect previous game installations — saving players from re-downloading! &#xNAN;Very useful for old launcher migrations to Game Launcher Cloud!

NEW - App Advanced Settings - Possible Previous Install Locations

When a player opens the launcher and no local installation is found, the launcher will now search a list of possible previous install locations to try to locate an existing game installation. If found, the launcher links to the existing files instead of requiring a manual locate or full re-download / installation.

How it works:

1. Configure possible install locations in App Advanced Settings on the Dashboard

2. When the launcher starts and no installation is detected in the current app, it searches the configured paths for the app

3. If a valid installation is found at any of the configured locations, the launcher uses it automatically as the installation path

4. Launcher verifies the files, if everything is up to date, can launch the game immediately

Key details:

Aspect	Detail
Configuration	Set from App Advanced Settings in the Dashboard
Search behavior	Launcher checks each configured path sequentially
Fallback	If no previous install is found, the user has to locate the installation manually
Multiple locations	Support for multiple paths — useful for games previously on other drives

How to test it:

1. Close the Desktop Launcher

2. Press WIN + R and type %LOCALAPPDATA%\GameLauncher\Settings

3. Delete the apps.json file

4. Open the launcher again

If the launcher automatically detects the installation, the path you configured is working!

Fixed — Launcher Failing to Start .exe Executables (Converted from .bat)

BUG FIX: The launcher now correctly opens and executes game files that were originally .bat files configured as executables.

An issue was discovered where the configured executable was actually a .bat file, causing a startup error (Launch failed) when the launcher attempted to run it. This has been fixed — the launcher now properly handles and starts the configured file regardless of its original format.

Fixed — Hidden Environments with Access Keys Not Appearing

BUG FIX: Hidden environments that require an access key are now correctly displayed after entering the correct key.

Previously, even after entering the correct access key, the environment did not appear in the desktop launcher environment dropdown on some PCs. This behavior has been fixed and valid environments are now shown as expected.

---

Fixed — Incorrect Installation Path Resolution

BUG FIX: The launcher now correctly respects the installation folder selected by the user.

Previously, if a user chose a custom directory such as C:\Game, the launcher incorrectly searched for the game inside C:\Game\Production. This has been fixed so the launcher uses exactly the path selected by the user without appending unintended subfolders.
