This is a very common issue with older versions of Autodata (such as v3.38, v3.40, or v3.45) running on modern versions of Windows (Windows 10 or Windows 11).

Here are the steps to resolve this issue, ordered from the most likely solution to the least. Close AutoData

Fix 6: Recreate the AutoData User Profile

Some versions store language settings in a local profile. Corrupted profiles cause this error.

  1. Close AutoData.
  2. Navigate to: 
    %APPDATA%\AutoData
    (Type that into File Explorer address bar.)
  3. Rename the folder to AutoData_old.
  4. Launch AutoData – it will recreate fresh profile files.
  5. If the error persists, also delete: 
    HKEY_CURRENT_USER\Software\AutoData
    from registry and restart the app to rebuild it.

Solution 1: Manually Correct the Registry Key

This is the most direct fix. You will navigate to the specific registry key that holds the language settings and either repair or delete it (forcing the program to recreate it).

Warning: Editing the registry incorrectly can damage your Windows installation. Always back up the registry before making changes.

Steps:

  1. Press Windows + R, type regedit, and press Enter.
  2. In Registry Editor, click File > Export. Name the backup "RegistryBackup.reg" and save it to your desktop.
  3. Navigate to the following paths (depending on your software version):
    • HKEY_CURRENT_USER\Software\AutoData\Settings
    • HKEY_LOCAL_MACHINE\SOFTWARE\AutoData\Language
    • HKEY_CURRENT_USER\Software\AutoData\Language
  4. Look for a value named Language, LangID, Locale, or UILanguage.
  5. If the value exists but is corrupted (e.g., contains symbols or a number like -1), right-click it and select Modify. Change the data to 1033 (for English US), 2057 (for English UK), or 1031 (for German).
  6. If the value does not exist, right-click in the right pane, select New > String Value, name it Language, and set the value to 1033.
  7. If the entire AutoData key is missing, try creating it manually: Right-click on Software, select New > Key, name it AutoData, then inside create the Language key and value as above.
  8. Close Registry Editor and restart the installation.

3. Preliminary Checks

Before diving into complex fixes, rule out basic issues:

  1. Run as Administrator – Right-click the AutoData shortcut → Run as administrator.
  2. Reinstall AutoData – Uninstall via Control Panel, reboot, then reinstall using the original CD or downloaded installer.
  3. Temporarily disable antivirus – Disable real-time protection during installation and first launch.
  4. Check Windows language settings – Go to Settings → Time & Language → Language & region – ensure your primary language matches the AutoData version (e.g., English for US/UK version).

If the error persists, proceed with the advanced solutions below. (Type that into File Explorer address bar

Fix 7: Disable "Controlled Folder Access" (Windows Defender)

Windows Security’s ransomware protection sometimes blocks registry reads for certain programs.

  1. Open Windows Security → Virus & threat protection.
  2. Click Manage ransomware protection.
  3. Turn off Controlled folder access temporarily.
  4. Run AutoData. If it works, add AutoData to allowed apps instead of disabling permanently.

A. Incomplete or Corrupted Installation

If a previous installation attempt failed, was interrupted by a power outage, or was canceled improperly, registry keys may be left half-written or missing entirely.

6. Use the Silent Install Switch (Advanced)

If the GUI installer keeps failing, try a silent install from an elevated command prompt:

AutoData_Setup.exe /quiet /norestart

Some versions accept /LANGUAGE=EN to bypass the registry lookup.

Fix 3: Grant Full Registry Permissions

If the key exists but can’t be read:

  1. In Registry Editor, right-click the AutoData key → Permissions.
  2. Select your username or Users group.
  3. Check Allow for Full Control and Read.
  4. Click Advanced → ensure ownership is set to your account.
  5. Apply and restart the software.
