Hello,

Thank you for your question and for reaching out with your question today.

The error message "[SC] StartService Failed 1275" typically occurs when there are issues related to driver signing or permissions. Here are some additional steps you can take to troubleshoot the problem:

1. Verify CodeSign certificate: Ensure that you have correctly signed the driver with a valid CodeSign certificate. Double-check the signing process and make sure that you are using the correct certificate.
2. Trusted Root Certification Authorities: Check if the root certificate authority (CA) that issued your CodeSign certificate is present in the Trusted Root Certification Authorities store on the target system. If it's not present, you may need to install the CA's root certificate manually.
3. Driver installation method: Ensure that you are using the correct method to install the driver. Depending on the Windows version and the driver type, there are different installation methods available, such as using an INF file, using the Device Manager, or using the PnPUtil command-line tool. Make sure you are following the appropriate method for your driver.
4. Driver package integrity: Check if the driver package is intact and not corrupted. Verify that all the necessary files and dependencies are included in the package. A corrupted or incomplete package can cause issues during the installation process.
5. Driver installation permissions: Ensure that you have sufficient permissions to install the driver. Administrative privileges are generally required to install drivers on Windows. Right-click on the command prompt or PowerShell window and choose "Run as administrator" to ensure elevated privileges.
6. Disable driver signature enforcement: If you are testing or debugging the driver, you can temporarily disable driver signature enforcement in Windows. This allows you to load unsigned or self-signed drivers. To do this, restart the system and press F8 during boot to access the Advanced Boot Options menu. Select "Disable driver signature enforcement" and then try loading the driver again.
7. Check Windows Event Viewer: Examine the Windows Event Viewer for any related error or warning messages that might provide more detailed information about the issue. Look for entries under "System" or "Application" logs that occurred around the time of the error.

By checking these aspects, you should be able to further diagnose and resolve the "[SC] StartService Failed 1275" error when attempting to load the driver with the sc command.
