Hi M, Revathi,

The error 0x3000064 is typically seen during Windows installation or upgrade processes and usually points to an incomplete or interrupted setup phase, often caused by storage, driver, or partition issues. Let’s go through a few checks to help you resolve it:

1. Disconnect unnecessary peripherals: Remove external drives, USB devices, or printers that might interfere during setup.
2. Run a disk check: Use chkdsk /f /r from an elevated Command Prompt to verify your drive’s integrity before retrying the installation.
3. Update storage and chipset drivers: Outdated or incompatible drivers can trigger this error during file copy or apply phases.
4. Verify disk space: Ensure there’s at least 20GB of free space on the system drive for the upgrade or installation.
5. Check setup logs: Review setuperr.log and setupact.log under C:\$WINDOWS.~BT\Sources\Panther\ for more details around the failure point.

If you confirm whether this happened during a Windows upgrade or clean installation, I can provide more specific next steps.
