WinOLS 4.7 is high-end professional software. Most versions circulating outside of an official EVC license are "timed" releases. The software’s internal security checks the current system date against a hardcoded expiration date in the program's license loader.

When your PC date passes that specific threshold, the software assumes the license has expired or that you are trying to bypass security, resulting in the "system date is wrong" lockout. Method 1: The "RunAsDate" Utility (Recommended)

The most effective way to fix this without messing up your entire computer's schedule (like your browser or other apps) is to use a utility called RunAsDate.

Download RunAsDate: It’s a lightweight, free utility from NirSoft.

Select the WinOLS Executable: Point the utility to your WinOLS.exe file.

Set the Date: Choose a date back in 2021 or early 2022 (depending on your specific build).

Create a Shortcut: Use the utility to "Create Desktop Shortcut."

Launch: Use this new shortcut every time you want to open WinOLS. The software will "see" the old date, while your Windows clock remains current. Method 2: Manual System Date Rollback

If you don't want to use third-party tools, you can change your Windows settings manually, though this is less convenient. Social post: WinOLS + "Your system date is

Right-click the clock in your taskbar and select Adjust date/time. Turn off "Set time automatically." Click "Change" under "Set the date and time manually." Set the year to 2021. Launch WinOLS.

Note: This method will likely cause "SSL/Connection" errors in your web browser (Chrome/Edge) because websites require a current system time to verify security certificates. Method 3: Checking the "Loader"

Many WinOLS 4.7 packages come with a specific Loader.exe. If you are trying to launch the software via the original WinOLS.exe icon, you will almost always get a date error.

Ensure you are launching the application through the provided loader, and ensure your antivirus hasn't "quarantined" the loader, as it is often flagged as a false positive. A Note on Stability

While version 4.7 is popular because of its 64-bit support and newer checksums, date-related errors are a sign of an unstable environment. If you use WinOLS for a professional business, the best way to avoid "Your system date is wrong" and potential file corruption is to use the official version from EVC.de.

However, for educational purposes and DIY enthusiasts, the RunAsDate method remains the gold standard for bypassing this specific error.

Part 1: Understanding the Error – It’s Not About the Real Date

First, let’s clarify a critical point: WinOLS Error 47 is almost never about your actual computer’s date being incorrect.

You might glance at your taskbar, see today’s correct date (e.g., May 2, 2026), and think, “But my date is right!” That is the core of the confusion.

WinOLS does not simply check your system clock against the internet. Instead, it uses a complex date-validation algorithm tied directly to its licensing mechanism. The error appears when the date as calculated by the license (dongle/emulator) does not match the expected date range coded into that license.
