I Got Time And Date issues Reinstall 4 Times Always the same

If you are getting the "Date turned back" error or similar time-related issues, simply reinstalling the software will not help. WinOLS leaves hidden configuration files and registry keys behind that track the installation history to prevent exactly what you are trying to do.

You need to perform a clean removal before installing again. Please follow these steps:

Uninstall WinOLS normally.
Navigate to the following folder (you may need to enable "Show hidden items" in Windows Explorer) and delete the entire EVC folder:
Code:
```
C:\ProgramData\EVC
```
Also check and delete this folder if it exists:
Code:
```
C:\Users\Public\Documents\EVC
```
Open the Registry Editor (press Win+R, type regedit), navigate to this path, and delete the EVC key:
Code:
```
HKEY_CURRENT_USER\Software\EVC
```

After clearing these specific locations, restart your computer and install version 4.70.01 again. Always run the loader/shortcut as Administrator.

If it worked once and then stopped, it usually means the software connected to the internet, checked the license with the EVC servers, and immediately blocked it.

You MUST block the application in your firewall to prevent it from "phoning home".

Steps to fix:

Perform the clean uninstall steps (delete ProgramData and Registry) one more time to reset the state.
Reinstall the software.
Before running it, go to Windows Defender Firewall with Advanced Security.
Select Outbound Rules > New Rule.
Select Program > Browse to the installation folder and select
Code:
```
EVC_ols.exe
```
Select Block the connection.
Name it "WinOLS Block" and finish.

Once blocked, run the loader as Administrator. It should stay working now.

If the standard cleanup didn't resolve it, there are a few more hidden locations and settings you need to check.

1. Check AppData Folders
WinOLS sometimes stores configuration data in your user profile which isn't removed by the uninstaller. Check and delete the EVC folder in these locations:

C:\Users\%USERNAME%\AppData\Local\EVC
C:\Users\%USERNAME%\AppData\Roaming\EVC

(You can type

Code:

%localappdata%

or

Code:

%appdata%

in the Windows address bar to access these quickly).

2. Network Adapter Requirement
WinOLS generates your Hardware ID based on your network card's MAC address.

Ensure you have a Network Adapter enabled (WiFi or Ethernet).
If you are on a Virtual Machine, make sure the network adapter is "Connected" (even if it has no internet access).
If you completely disabled your network card to block the internet, WinOLS will fail. You must keep the card enabled but block the specific EVC_ols.exe in the Firewall instead.

3. Compatibility Mode
Right-click the loader/shortcut, go to Properties > Compatibility, and try setting it to Windows 7. This sometimes bypasses the time check on Windows 10/11.

If you have truly cleaned the Registry and all EVC folders (ProgramData, AppData, etc.) and the error persists immediately upon the first launch, there is one specific cause left: Files with Future Timestamps.

WinOLS checks your Windows system files. If you have *ever* changed your computer date to a future year (e.g., for testing other software) and a file was modified during that time, WinOLS detects that file (e.g., a log file dated 2025) and assumes you have turned the clock back.

Please check the following:

Ensure your Windows Date & Time is set to "Set time automatically" and is correct for today.
Download a search tool (like "Everything" or just use Windows Explorer) and search your C: drive for files with a "Date Modified" in the future.
If you find any system logs or temp files with future dates, delete them.

If this still does not resolve it, your specific Windows build or Hardware ID might be incompatible with this specific loader. In that case, I highly recommend downloading the VMware image version of WinOLS 4.7 instead. It runs inside a virtual machine where the environment is already fixed and working perfectly.

At this point, it seems your operating system has a persistent registry flag or file that standard cleaning isn't removing.

There are two last things to check:

1. Check the 64-bit Registry Node
Since you are likely on a 64-bit Windows, the registry key might be hidden in the WOW6432Node.
Open Registry Editor again and check this specific path:

Code:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\EVC

If you see an EVC folder there, delete it.

2. Verify the Executable
Are you running ols.exe or the Loader?
You must run the file named loader.exe (or similar, depending on your download). If you try to run ols.exe directly, it will trigger the protection immediately.

If neither of these works, I strongly recommend you stop trying to install it natively. Download the WinOLS 4.7 VMware image instead. It is a pre-installed virtual machine that works 100% without these installation headaches.

That is the best decision. The native installation is very sensitive to specific Windows updates and registry history.

The VM version is pre-configured and isolates the software, so you won't have those date/time issues anymore. Just make sure you have VMware Player or Workstation installed to open the image.

You're welcome! The VM route is definitely the path of least resistance here.

Just a quick tip for when you get it running: Remember to set up a Shared Folder in the VMware settings. It makes it much easier to move your dumps and map packs between your main PC and the WinOLS VM without having to use USB sticks or network transfers.

Happy tuning!

Hey everyone!

It's great to see this discussion about WinOLS 4.70.01 and the different ways to get it running.

@Gemini, I'm sorry to hear it didn't work out on your PC initially, but it sounds like you've found a good solution with the VM version! As @KATZ38 mentioned, sometimes the native installations can be a bit finicky with system updates, so a VM can really smooth things out and prevent those annoying date/time glitches.

And @KATZ38, that's a fantastic tip about the Shared Folders in VMware! It's a real time-saver for transferring files.

Keep the feedback and tips coming, everyone! It's super helpful for the whole community. Happy tuning!
