Issue running Chrome in unattended mode

Posted on by powerdevkris 159 Season of Giving Solutions 2025

Hi,

 

This was my first time testing my desktop flow in unattended mode. The flow requires to open a website and click a download link once the process is done. Everything works fine on attended mode but getting this error on unattended.

 

Problem while executing action 'LaunchChrome'. Failed to assume control of Chrome (Communication with browser failed. Try reloading extension).  

 

Using this action to launch Chrome

Should i do this another way, or this type of process will not run on unattended mode?

    Hi @powerdevkris 

     

    Could you please confirm whether the extension is installed correctly

     

    Looking at the error, I think it is the issue with chrome extension in unattended machine in chrome browser

     

    Thanks & Regards,

    Could you try this ?

     

    1. Navigate to this via cmd and run it with SetupExtensions.exe /chrome.
    2. Make sure your chrome tabs are closed.
    3. Try re running the bot again

    The SetupExtensions.exe is not recognized as an internal command. Do i need to find it on a specific directory?

    Hi @powerdevkris

     

    Go and remove the chrome extension after re install it may be you will get resolved

    @powerdevkris It probably has to do with the Power Automate Desktop installed from Microsoft Store, please uninstall it and install via MSI from the link below, and it should work.
