EOS Webcam Utility pro wont open

[devp16]

I'm having problems with the webcam utility. I used it last week to stream on Twitch with no issues, but today the webcam utility isn't detecting my camera at all. The USB icon with a red X that usually appears when a camera is not connected is notably missing.

So I tried opening EOS Webcam Utility Pro to see if I had to adjust a setting within the program, and it just won't open. Attempting to open it creates multiple processes but it never manages to opens a window. 

The last thing I tried was uninstalling and reinstalling all Canon software on my pc, including drivers, but it still isn't working. I'm frustrated and out of ideas at this point. Any help would be appreciated!

t’s begin with telling us which camera you have.  What brand of computer to you have and which Operating System are you running?  Has your OS been recently updated?

Make sure that you have Bluetooth and Wi-Fi functions disabled.  Use the supplied cable.  Do not use any USB port adapters.

The motherboard firmware in some computer brands need for you to manually start the EOS Utility 3 the first time you use it.  Think of it as a jump start.

If the OS detects your camera after turn it on and asks you what action should it take, then select “Take No Action.”

Are you running an commercially available off-the-shelf computer?  Or, is your computer a desktop that you have built from a motherboard?

Same thing here. Did you ever get to fix this?

Hi, Anes!

Try the following to resolve this frustrating situation:

• Make sure you are using the latest version of the EOS Webcam Utility Pro from https://canon.us/ewu 
• Verify your camera is listed on the COMPATIBLE CAMERAS list - it must be the exact model.
• You must be in the United States.

If all of these things are true and you still have problems using the EOS Webcam Utility Pro, I recommend calling phone support for one-on-one troubleshooting at 1-800-OK-CANON (800-652-2666). Our support team is available Monday through Friday from 9 a.m. to 6 p.m. (ET).
