If you want to completely avoid date-related errors, hardware lockups, and security vulnerabilities, consider upgrading to an official, licensed version of WinOLS from EVC electronic, which receives automatic cloud updates and requires no system clock manipulation.

If you are still using (the legendary “golden” version many tuners keep as a backup), you might have recently been greeted by a frustrating pop-up:

WinOLS writes temporary timestamps into your system registry. If a system crash or power failure occurs while editing an ECU map, a "future timestamp" can become trapped in the registry cache, triggering a permanent lock.

Open the Windows Start menu, type , right-click it, and choose Run as administrator .
