The "Your system date is wrong" error in WinOLS 4.7 typically occurs because the software's internal security certificate or license check detects a mismatch with your computer's current date, often due to an expired activation. How to Fix the Error
To resolve this, you generally need to ensure your Windows time settings are synchronized or manually adjusted to match the software's requirements: Sync Time Automatically:
Right-click the clock in your taskbar and select Adjust date and time.
Ensure Set time automatically and Set time zone automatically are toggled On.
Click Sync now under "Synchronize your clock" to force an update from Windows servers. Manual Date Adjustment:
If the software is a specific older version, it might require a specific historical date. Turn off "Set time automatically" and manually set the date to a time closer to when that version was released. Run as Administrator:
Right-click your WinOLS shortcut and select Run as administrator. Some licensing checks fail if the app lacks sufficient permissions to read system time data. Download & Reinstallation
If the date fix doesn't work, the installation may be corrupted. Professional users are recommended to download the latest stable version (currently WinOLS 5) directly from EVC Electronic to ensure proper licensing and support. For a clean reinstall of version 4.7, follow these steps:
Navigate to C:\Program Files (x86)\EVC and delete the existing WinOLS folder.
Run the installer again, ensuring you uncheck "Launch WinOLS" at the end of the setup.
