WinOLS 47 relies on older Visual C++ runtimes. If missing, the date check fails silently.
Run WinOLS 47 inside a Windows 7 Virtual Machine (using VMware or VirtualBox).
The "System date is wrong" error in WinOLS 4.7 is less about the clock on your taskbar and more about the trust the software has in the operating environment. It is a digital detective, looking for clues that the timeline has been tampered with.
If you are seeing this, the software has likely caught a contradiction between "file system time," "BIOS time," and "execution time." The solution is almost always to wipe the slate clean, ensuring that the software sees a pristine, linear timeline from installation to execution.
How to Fix "WinOLS 4.7 Your System Date is Wrong" During Installation
If you are trying to install WinOLS 4.7 (often the "VMware" or "cracked" versions) and you are hit with the error "Your system date is wrong, please correct it," you aren't alone. This is a common security trigger in the software that prevents it from running if it detects a mismatch between the internal license expiration and your computer's clock.
Here is a straightforward guide on why this happens and how to bypass it. Why Does This Error Occur?
WinOLS 4.7 is highly sensitive to timestamps. The error usually triggers for one of two reasons:
License Expiration: The version you are using has a "hard-coded" expiration date. If your current calendar date is past that point, the software locks itself.
Sync Issues: If you are running WinOLS inside a Virtual Machine (VMware), the VM often syncs its time with your host computer (the main PC). If that date doesn't match what the software expects, it fails. Step-by-Step Solutions 1. The Manual Date Rollback (Easiest Fix)
The most common "fix" for unofficial versions of WinOLS 4.7 is to manually set your computer’s date back to a time when the software was active. winols 47 your system date is wrong install
Disconnect from the Internet: This is crucial. If you stay connected, Windows will automatically re-sync the time.
Change System Date: Go to Settings > Time & Language > Date & Time. Toggle Off: Turn off "Set time automatically."
Set Date: Change the date to January 1, 2021, or early 2022. Restart WinOLS: Try the installation or launch again. 2. Disabling Time Sync in VMware
If you are using a pre-configured WinOLS VMware image, the VM is likely trying to grab the "real" time from your desktop. You need to sever this link. Shut down the Virtual Machine. Go to the folder where your VM files are stored. Locate the .vmx file (the configuration file). Open it with Notepad. Add or edit these lines to say FALSE: tools.syncTime = "FALSE" time.synchronize.continue = "FALSE" time.synchronize.restore = "FALSE" time.synchronize.resume.disk = "FALSE"
Save the file and restart the VM. Now, when you set the date inside the VM, it will stay put. 3. Using "RunAsDate" Utility
If you don't want to change your entire system clock (which can break web browsers and other apps), use a small utility called RunAsDate. Download RunAsDate (from NirSoft). Select the WinOLS executable (.exe).
Choose the date you want the software to "see" (e.g., 01/01/2021).
Create a shortcut. From now on, using that shortcut will launch WinOLS with the "fake" date while your actual PC remains on the current date. Important Considerations
Checksums: Be careful when using outdated versions for actual ECU tuning. If the date-fix version is unstable, it could result in bad checksum calculations.
Antivirus: Many "fixes" for this error are flagged by Windows Defender. Ensure you are downloading tools from reputable sources. WinOLS 47 relies on older Visual C++ runtimes
The Pro Alternative: If you are using WinOLS for professional work, the official version from EVC.de avoids these "system date" headaches entirely and provides necessary updates for newer ECU protocols.
To get past the "system date is wrong" error, disconnect from the web and roll your clock back to 2021. If you're on a VM, make sure to disable time synchronization in the .vmx settings so the clock doesn't jump back to the present day.
The "Your system date is wrong" error in WinOLS 4.7 is a common issue typically encountered during the installation or launch of unlicensed or modified versions of the software. This error occurs because the program includes a "time-bomb" or a validity check that compares your current computer date against a specific hardcoded expiration date. 1. Identify the Cause
This error is rarely about your actual CMOS battery or Windows time settings. Instead, it is a built-in security measure in EVC WinOLS. If the software detects a date significantly newer than its release window, it assumes the license has expired or the trial period is over and blocks access. 2. Standard Fix: Synchronize Windows Time
Before trying advanced bypasses, ensure your Windows clock is actually correct. Right-click the Time/Date in your taskbar. Select Adjust date/time. Ensure Set time automatically is toggled ON.
Click Sync now to force an update from the Windows Time server. 3. Advanced Fix: Date Simulation (RunAsDate)
If the error persists (common with version 4.7), you may need to trick the software into thinking it is running on a previous date.
Download RunAsDate: This utility allows you to run a specific program at a fixed date and time without changing the system clock.
Configure the Loader: Point RunAsDate to your WinOLS.exe file.
Set the Date: Set the date back to early 2021 or 2022 (depending on the specific build of your 4.7 installer). Run WinOLS 47 inside a Windows 7 Virtual
Create a Shortcut: Use RunAsDate to create a desktop shortcut so the software always launches with this "frozen" time. 4. Installation Path Check
Some versions of WinOLS (like 2.24 or 4.7) are sensitive to installation directories. If you are using a 64-bit system, ensure the program is installed in C:\Program Files\ rather than C:\Program Files (x86)\, as the internal loaders often hard-code the primary path. 5. Clear Database Indexes
If the software opens but crashes with a date-related database error, you might need to reset the index. Go to your WinOLS project folder. Right-click in the Projects list.
Select Delete + Create index database to refresh the project links.
✅ ConclusionThe "system date is wrong" error is a software-side validity check that can be resolved by synchronizing your Windows time or using a date-simulation utility to match the software's expected era. If you'd like, I can help you: Find the specific RunAsDate settings for your version.
