Love to play with Windows 11 and 10. Suggestion - Going for Registry change or system files edit then remember to take a backup or create a restore point before Starting.

  1. Thank you for the info. I observed this error under Window 7 (Nov 2021) about a month after installing the Canon camera CD (Oct 2021). There are a few components called Canon Zoom Ex… I went into control panel, click program, then click the Canon camera CD software and uninstall all of them, restart the PC. The problem is solved. I suspect the problem is caused by the Zoom Ex component looking for an external USB pen with certain photos on it. I also delete the Zoom app. Many thanks. Problem solved.
