zfcAgent.exe Error ZCefAgentSystemError

Hello everyone,

For whatever reason, a few people at my company are having this error box open up multiple times when first opening Zoom. A clean uninstall and reinstall doesn't fix the issue. SFC scannow doesn't either. The agent is trying to open up the libcef.dll file in the "cef_x86" folder in the Zoom appdata folder. I have also tried renaming the folder to "zoom.old" to have it recreate the folder. Furthermore, I have tried copying the "cef_x86" folder over from another user who doesn't seem to be having the issue.

Anyone have experience with this issue that can help me out?

Here is the error in event viewer.

I have had the same issue since Monday! Our appdata is redirected to a network location and I know version 5.8.4 changes the way Zoom looks at appdata. The only way I have been able to fix the issue is revert back to version 5.8.0 and the error goes away. 5.8.4 was working fine up until Monday this week! We are also a VDI environment using ZoomVDI application. Is that the same case for you?

Could you install the Microsoft Edge WebView2 Runtime on the issue VM then check whether the issue can be reproduced or not? The installation of this APP needs admin previledge. You can download the WebView2 Runtime from the following link based on the OS version of the VM.

Are you using the ZoomVDI version. That's what we are using.

What is the VDI? We just deploy the Zoom MSI via PDQ deploy

We are on version 5.8.4 Zoom VDI. Does your company do appdata redirection at all?

Yeah, all of our appdata is redirected unfortunately.

Ours is also, I think it has something to do with the appdata redirect. I have a ticket in with support and haven't made mush progress with them yet.

Hello Guys,

the same issue here.

We also have redirected our Appdata folder. We have the same issue since Monday as well.

The first answer of the Zoom Support was It's not their fault, its a dll of Windows.

I'm happy, that it seems to not only our problem.

Greetings from Germany 😉

Hello yuting_ke,

we installed the Webview2 Package as a test at 2 of our Clients.

The Error seems to be fixed.

How is the further procedure?

Will you release an update of Zoom?

I'm going to install it to and see if it fixes the issue, I just find it weird that we have to install this even though it was working find for a couple months and just recently broke as of Monday! We made no changes in our environment and the support ticket I have open keeps blaming our environment even though I point them to this thread showing other users having the issue.
