EOS Webcam Utility PRO does not work after upgrade to Windows 11

mgreis — Sat, 21 Feb 2026 14:16:19 GMT

I used the original EOS Webcam utility with my Rebel T8i / 850D for five years, mostly for Zoom. It stopped working when I upgraded to Windows 11. I was told that I had to use the newer EOS Webcam Utility Pro.

I installed it and paid for a subscription. I uninstalled the original EOS webcam utility. I checked the installed applications to confirm that the old utility is no longer installed. The camera connects to the system, but all I see is the the B&W EOS Webcam utility splash screen when I start a Zoom meeting. I have rebooted and reinstalled the software (more than once). I've tried connecting the camera directly to my Lenovo laptop as well as to the USB hub I've been using with the webcam. Nothing.

Where do I go from here? It's extremely frustrating to have paid for a subscription and have no support.

Thanks for any help anyone can offer.

Have you called Canon support at 1-800-OK-CANON?

Hi John and thanks,

Yes, it finally occurred to me to try them. The support page is keyed to Canon hardware, so it hadn't occurred to me that they would be willing or able to help me. They were, however. We got it working, but neither I nor the support rep nor I quite figured out how. I think we unplugged and re-plugged the camera from its power source, but I didn't have to reboot my computer or any of the software. It just started working. I can't therefore offer much assistance to others running into problems.
