If it says [SC] DeleteService SUCCESS , the conflict is resolved.

Many older applications bundle outdated versions of WinDivert (like version 1.4.0 or older) that are incompatible with newer Windows 10 and Windows 11 builds.

On the tab, look at the bottom. If you see a message saying "This file came from another computer and might be blocked," check the Unblock box and click Apply. 5. Use the "Fresh Start" Sequence

Press to permanently delete them. (If Windows says some files are in use, click Skip ). Summary Troubleshooting Checklist What it Fixes sc delete windivert Clears stuck background services Run as Administrator Fixes permission denial errors Antivirus Exclusion Stops security software from deleting driver files Disable Memory Integrity Stops Windows from blocking unsigned driver binaries

If a previous application closed improperly, the WinDivert service might still be marked for deletion or stuck running in the background.

The WinDivert driver is a kernel-mode driver that requires administrative privileges to install. During installation, the driver attempts to load into the Windows kernel. If the installation is successful, the driver creates a network interface that can be used to capture and modify network traffic.

Copy and replace these files inside the folder of the application you are trying to run (e.g., the GoodbyeDPI folder). 4. Allow Through Windows Defender / Antivirus

The error is a safety mechanism by Windows to prevent network conflicts. While the prompt tells you to restart, the issue is usually that a background process is the driver file immediately upon boot. The "Clean Boot" method (Step 1) resolves this issue in 90

When you run a WinDivert-based app, it attempts to install a kernel-mode driver on the fly. If the driver is already partially loaded in a "stuck" state, or if an older version's service is still registered, Windows blocks the new installation. The system suggests a restart because that's the easiest way to clear out resident drivers, but sometimes the "zombie" service survives even a reboot if it's set to auto-start or if the registry is corrupted. Common Fixes (No Restart Loop Required)

Choose the folder where your application (and its accompanying windivert.dll and windivert64.sys files) is located.

Before we dive into the solutions, it's helpful to understand the most common reasons this error occurs. This will help you choose the most effective fix.

A previous instance of the WinDivert service is still running in the background or is marked for deletion by Windows.

The WinDivert (Windows Packet Divert) driver installation often fails with a persistent restart loop if there are orphaned services, conflicting registry entries, or missing dependencies. Because WinDivert is installed "on-demand" by applications

To resolve the "WinDivert driver cannot be installed" error without a full restart, you can manually force the removal of old service handles and registry entries that are blocking the new installation. 1. Force Stop and Delete the Service
