This guide explains how to resolve errors related to the Lite Sync Windows extension on the desktop application kDrive.

Check for the presence of the extension

Before performing any operations, make sure the extension is registered by the system:

1. Open the Settings of Windows.
2. Go to the Apps section, then Installed apps.
3. In the search bar, type "kDrive".
4. Check that the item kDrive Windows Explorer Extension Package appears in the list:
   

Error of type "Unable to start Lite Sync"

This error usually occurs when the Windows Explorer extension is missing or corrupted.

Manual reinstallation of the extension

If the extension does not appear or does not work, you can install it manually without reinstalling all of kDrive:

1. Close the kDrive application completely (check that it is no longer in the notification area).
2. Open your file explorer and go to the folder:
   C:\Programs\kDrive\shellext\AppX\
3. Double-click on the file:
   FileExplorerExtensionPackage_3.8.1.0_x64_arm64.msixbundle
4. A specific installation assistant for the extension will open. Follow the steps.
5. Restart your computer to validate the integration.

If the problem persists

If, despite the manual installation, the LiteSync option remains unavailable:

• Antivirus: Check that your security software is not blocking the processes located in C:\Programs\kDrive\.
• Conflicts: Other cloud services (such as OneDrive) can sometimes conflict with kDrive icon extensions.
• Logs: If necessary, send the kDrive logs (in Debug mode) to Infomaniak support.
