Pre-install steps

  1. Backup any important files.
  2. Disable antivirus and real-time protection temporarily (re-enable after install).
  3. Ensure Windows is updated: Start > Settings > Update & Security > Check for updates.
  4. Create a system restore point: Control Panel > Recovery > Configure System Restore > Create.

Step 7: Final Optimization for Windows 10

To make AutoData 3.40 run smoothly for daily use:

  1. Turn off fullscreen optimizations: Right-click AutoData.exe > Properties > Compatibility > Check "Disable fullscreen optimizations".
  2. Set Windows 10 to Game Mode: Add AutoData.exe to the Windows Graphics settings (Settings > System > Display > Graphics settings) and set it to "High performance".
  3. Create a batch launcher: Create a new text file on your desktop named RunAutoData.bat. Edit it with:
@echo off
cd /d C:\AutoData\340
start /affinity 1 AutoData.exe
exit

This forces the software to run on a single CPU core, preventing random crashes. Important Disclaimer: AutoData 3
