Safe next steps
- For 0x80073D3F (ERROR_INSTALL_DRIVE_NOT_FOUND), identify the exact target volume for the app installation or move and whether Windows still sees it.
- Check free space, online state and the Store or AppX deployment event before retrying the publisher’s package.
- If the volume is corrupt or disconnects, protect data before reset or reformat actions.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
