Error clicking on "required credentials" for a digital certificate

Hello.
I’ve switched computers and now have Windows 11 with:
Chrome: Version 148.0.7778.168 (Official Build) (64-bit)
Edge: Version 148.0.3967.70 (Official Build) (64-bit)
UiPath Studio: 2026.0.191
I’m trying to log in to a website that uses a digital certificate. Once I click on the certificate, a new window appears asking me to accept the credentials. When I try to click “Accept,” it tells me that elevated privileges are required. It tells me to run UiPath as administrator, but if I run it from the icon in that mode, I get the error shown in the attached image, and the process doesn’t start.
I used this type of process on my old PC and never had any problems.

Hi @Aguirre ,

Microsoft Windows January 2026 security updates introduced new restrictions that prevent certain applications from auto-filling credentials. As a result, the Robot could no longer interact with the Windows Security dialog (CredentialUIBroker.exe).

For more information, see this Microsoft article: New behavior restricting certain applications to autofill credentials introduced by the Windows January 2026 security update.

We delivered hotfixes that restore automation support for:

For the Studio/Robot STS, the issue has been solved starting with Studio/Robot 2026.0.192.

Additionally, to enable Indicate/Edit Target for the Windows Security dialog in UiPath Studio, the workflow must use UiPath.UIAutomation.Activities 25.10.29 or 24.10.18 (or higher).

Best regards,
Luiza

Hi, the quick and easy solution was to disable this option during installation. That’s why the screen I had to accept didn’t appear. Since I only have one certificate on a computer without access for other people, I didn’t see any problem removing that warning and being able to continue working. I still need to try what you suggested.
Thank you very much, and sorry for the delay in responding.
