| Error Code | Likely Cause | Detailed Explanation | | :--- | :--- | :--- | | | Driver Signature Issue | Windows requires all kernel drivers to have a valid digital signature for security. Version 2.2 of WinDivert has a valid signature, but older or custom-compiled versions may not. This error signifies that Windows is blocking an unsigned or improperly signed driver. | | Error 0x80041017 | WMI Repository Corruption | This specific error code points to a problem with the Windows Management Instrumentation (WMI) repository. This repository stores information about system components, and when it's damaged, it can prevent the proper installation of software and drivers. | | System Error 5 | Insufficient Administrative Privileges | Installing a kernel driver requires the highest level of access. If the application isn't run "as an administrator," the operation will be blocked, resulting in an "Access Denied" error. | | System Error 1275 | Driver Blocked by Security or Environment | This error is often triggered by security software (antivirus) that misidentifies WinDivert's behavior as suspicious. It can also occur in unsupported virtualization environments or if there's an architecture mismatch (trying to use a 32-bit driver on a 64-bit system). | | System Error 2 | Missing Driver Files | The application cannot find the necessary WinDivert32.sys or WinDivert64.sys driver files in its directory. This can happen if the download is incomplete or if the files are accidentally deleted. | | N/A | Memory Integrity (Core Isolation) | A Windows security feature called "Memory Integrity" (part of Core Isolation) can conflict with older or incompatible drivers, including versions of WinDivert, preventing them from loading. | | N/A | File System Interference or Conflicts | The driver installation can be blocked if the related files are currently "in use" by another process. This often happens if a previous instance of the application didn't close properly, leaving the driver locked. | Remove Dangling Driver Files This is a very
