naveed_raza — Sat, 13 Dec 2025 12:54:19 GMT

Unable to attach to the chrome which is open in guest mode using regular application modeler in Blue prism 7.5.

And , new enhancement application modeler is able to detect the Chrome which is open in guest mode , its not showing up in the list.

@Michael_S - is this something you can check with the team , which is not identifying ?

Guest Chrome mode is not showing up in the list

If we open Chrome in multiple profiles then, the profile which we opened first that only showing in the list and attaching to that only using both old and new application modeler.

@naveed_raza If you're trying to use browser mode, I assume that won't work because the Blue Prism Browser Extension isn't available in Guest mode. You could attach as a Local Desktop application type instead and use spy modes like Win32, UIA, and AA.

However, if you are trying to use the new Chromium mode, I think the one thing you're missing is that you have to initially launch the browser using the right flags. There are at least 2 of them (remote debugging port and user data directory), but those are handled automatically if you launch using Blue Prism. I would imagine there are two ways to do this, but let me suggest the easier way. Have Blue Prism launch the browser using a Chromium mode object and add the command line parameter "--guest" after the URL you are launching. Here's my example below:

I tested this on RPA Challenge successfully in Guest mode just now to make sure it does work.

Thank you @david.l.morris - for checking on this , guest mode i will try, if i have multiple chorme profile?

- Open chrome in multiple profiles (profile1, and profile2)

- i have open rpa challenge site in profile 1 and profile 2

- in application modeller 2 things ( in modern application modeller , if i click on refresh then its showing only one profile which is opened first) and if i try attach its attaching only to profile 1 rpa challenge site,

i think it through error stating that multiple window identified.

I have no experience automating windows of two different profiles at the same time. And I rarely try to automate two windows at the same time anyway even if it's possible.

its very rare to automate on multiple profile window.

in our system if we have multiple chrome profiles , how we can launch the chrome using using blueprism with specific profile or with guest ?

what is the recommended way to launch the chrome browser ?

It is important for you to specify what application type you're trying to use, especially now that Chromium mode is out. I'll show both though.

Chromium Mode using Guest Profile

It may be possible to launch a specific profile in Chromium mode. I don't know. You could just try out changing around the inputs, but I would think the target profile would have to be in the target user data directory and cannot be in the default data directory since this feature relies on using a non-default user data directory for the mode to work in Chrome.

Browser Mode using Specific Profile (Non-Guest)

To determine the name "Profile 2", I had to figure out what the underlying name was of the profile. That was here for me: "C:\Users\davem\AppData\Local\Google\Chrome\User Data". The display name of my profiles are different from the actual names. The actual names look to be Profile 1, Profile 2, etc. And there are folders in that User Data directory reflecting that.

@david.l.morris - thank you so much Dave in digging into this, i will try with multiple situations by applying your logic to see how chromium mode is behaving with traditional and modern application modeler and will share my thoughts and feedback here.
