Failed to asssume control of browser (Edge and Chrome) in unattended mode

(0) ShareShare

Posted on by
Hello everyone,
 
We are currently transforming our Power Automate Desktop flows from attended to unattended on a virtual machine. However, in both browsers (Edge and Chrome) when running the flows unattended Power Automate Desktop runs into the error of failing to assume controle of the browser (Edge/Chrome). We don't experience this problem when starting the flow attended on the virtual machine. Only when we start the flow unattended on this virtual machine.
 
The version of Power Automate Desktop is: 2.51.00233.24350 (Microsoft Store Version: 11.2412.242.0) 
The version of the extension is: 2.51.0.25
 
Would be great if someone can point us in the right direction. Also, please don't hesitate to contact us for any further clarifications.
 
Kind regards,
 
Bram van den Bemt

    The problem likely lies in the configuration of the browser extension, VM settings, or user session management.
