WinOLS often queries the system time directly from the hardware layer (the BIOS/UEFI) rather than trusting the Windows API entirely.
If the preliminary checks failed, proceed through these solutions in order.
If you cannot update, create a script that forces a correct date environment.
Save the following as launch_winols.bat:
@echo off
:: Save current date
set current_date=%date%
:: Set a known good date (e.g., 2017-06-01)
date 2017-06-01
:: Launch WinOLS
start "" "C:\Program Files (x86)\EVC\WinOLS\WinOLS.exe"
:: Wait 5 seconds for the software to bypass date check
timeout /t 5 /nobreak >nul
:: Restore real date
date %current_date%
exit
Run this batch file as Administrator each time you launch WinOLS.
Run WinOLS 47 inside a Windows 7 Virtual Machine (using VMware or VirtualBox).

Most instances of this error can be solved by refreshing your Windows Time settings:
Enable Automatic Sync: Go to Settings > Time & Language > Date & Time. Toggle "Set time automatically" to On. Run this batch file as Administrator each time
Verify Time Zone: Ensure "Set time zone automatically" is also On. If it is incorrect, turn it off and manually select the correct zone from the dropdown menu.
Manual Synchronization: Click the "Sync now" button under "Synchronize your clock" to force an immediate update from the Microsoft time server. Troubleshooting Persistent Errors
If the error remains after syncing, try these advanced steps:
Check Windows Time Service: Press Win + R, type services.msc, and find Windows Time. Ensure the status is "Running" and the startup type is set to "Automatic".
Internet Time Settings: In the Control Panel, go to Clock and Region > Date and Time > Internet Time. Click "Change settings" and ensure "Synchronize with an internet time server" is checked.
Replace CMOS Battery: If your computer loses the correct time every time it is powered off, the CMOS battery on your motherboard (usually a CR2032 coin cell) may be dead and needs replacement.
Administrative Rights: Ensure you are running the WinOLS installer as an Administrator to allow it to verify system parameters correctly.

Before diving into fixes, it is crucial to understand why WinOLS 47 checks your system date. This is not a simple clock battery issue.
WinOLS uses a time-based license validation system. Unlike modern subscription software that phones home to a server every few minutes, older versions (including v4.7) rely on local system time to verify trial periods, license expiration, and software integrity.
