Ensure the installer file ( WinOLS_Setup.exe ) is saved to a local directory, such as your Downloads folder. Step 2: Run the Installer
Go to and configure:
Antivirus software and aggressive firewall settings frequently flag automotive tuning software components during installation. Disconnect your computer from the internet temporarily.
Installing requires precision to ensure the software communicates seamlessly with your tuning hardware and that your checksums and maps calculate accurately. Below is a comprehensive, step-by-step breakdown of how to install, configure, and optimize WinOLS 4.7 on your Windows PC. Phase 1: System Requirements and Preparation Winols 4.7 Install
If you are a registered EVC customer, the registration wizard will now appear. Enter the customer code and password provided to you by EVC, and check the "remember password" box. If you are just training, the free demo version can be launched without credentials (though saving files is disabled). Phase 5: Initial Configuration and Best Practices

For tuning shops and businesses, WinOLS can be set up for network use. This process involves installing WinOLS on each individual workstation. You can then create a shared directory on a server (e.g., "WinOLS data") for car projects and ECU binary files. On each workstation, you need to point WinOLS to this shared directory via the configuration menu ( Miscellaneous > Configuration > Paths > Eprom-Data Path ). Keep in mind that checksum DLLs, which are crucial for the software's functionality, cannot be stored on a network drive; they must be installed locally on each computer.
