Since the update of edge chromium to version 84.0.522.40, we have this error after browsing sites in internet explorer compatible mode: Sharepoint 2013 or others
It's the same with Beta, Dev or Canary version, Windows 10 1809 or 1909.
"Cannot find http://--dualenginehist" Make sure the path or Internet address is correct"
Have you the same problem? Or a solution?

Seeing the same thing here, just started this morning. Any site that is in the IEmode list does this.

just to clarify a bit, we are using 84.0.522.40, and have been since we started rolling out (about 4 weeks now), this issue did not exist until today. We have also not applied ANY updates except Windows defender updates (which are set to automatically approve).

We opened a case with Microsoft. They can reproduce it and it is related to a IE GPO: https://gpsearch.azurewebsites.net/#1737
If you remove this setting the error disappears.
They are working on a permanent solution.

I've just had a coworker show me that error. It also started after the installation of Edge 84.0.552.40.
OS is Windows 10 Enterprise 1909 UBR 900 (June updates).
So far I only know about 1 affected installation/user and I cannot reproduce the issue on any of my test systems. Really weird.
I've opened a case with Microsoft about it. Let's hope this gets fixed fast before it spreads.

I have a solution:
Check if this value exist: "AutoSearch" in:
Registry Hive : HKLM or HKCU
Registry Path : Software\Policies\Microsoft\Internet Explorer\Main or Software\Microsoft\Internet Explorer\Main
And delete this

@Chris1215 Ohh, nice. Thanks for the update.
I just tried that and it does indeed fix the issue. And if you add the registry key it also creates the issue. So I can finally reproduce the issue on my system, sweet.
I had just scheduled a Teams session with a Microsoft support engineer. I'll forward your findings to him and let him know where the issue comes from.

Thank you, this did fix the issue here as well. One does have to ask though, how you found this? Seems like a pretty obscure reg value. Care to share your process? I'm also a bit curious as to how that key was created because apparently it didn't exist before yesterday, or something changed on the backend with Edge because we did not see this until yesterday.
I also rolled a client back to IE, then re-applied edge and the problem disappeared.

Hi all, seems to be fixed in 84.0.522.48, no official confirmation from Microsoft so far.

Can confirm that 84.0.552.48 is supposed to have fixed the issue, according to the Microsoft support engineer I've been in contact with regarding this issue.
