Autodata 3.40 Change Language To English May 2026

Autodata 3.40 is a legacy diagnostic software widely used by automotive technicians for wiring diagrams, service schedules, and repair manuals. Because many versions found online are pre-configured in specific languages (often Greek or Spanish), users frequently need to manually redirect the software to its English resource files. Direct Method: Modifying the Configuration File

The most reliable way to change the language is by editing the language.ini file located within the software's installation directory.

Locate the Folder: Navigate to the installation path, typically C:\ADCDA2\ or C:\Program Files\Autodata\.

Find the INI File: Look for a file named language.ini or settings.ini.

Edit the Code: Open the file with Notepad. Find the line that says Language=XX (where XX is a number).

Change to English: Replace the existing number with 1 or 01.

Save and Restart: Save the file and relaunch the application. Alternative: Replacing Resource Files autodata 3.40 change language to english
