Microsoft Edge (Chromium) support

Updated on October 19, 2022

Interrogate and automate applications that run on the Microsoft Edge browser by using the Pega Browser Extension along with the Universal Web Adapter in Pega Robotic Automation.

Keep in mind the following considerations as you use Robot Studio to interrogate and automate Microsoft Edge.

  • The Pega Edge extension is backwards compatible; the newer versions of the extension work with older versions of Robot Studio.
  • You can include multiple concurrent adapters. For more information, see Using multiple Chrome or Edge adapters within a Robot Studio solution.
  • You can automate the File Open, File Save as, and Print dialogs in Edge in applications that use the Universal Web Adapter. You can also automate Edge permission dialogs such as the Allow multiple files to be downloaded and Allow website to use your location dialogs. For more information, see Automate dialogs in Chrome and Edge.
  • You can interrogate rows of data and cells within those rows. Use cloning to work with tables. For more information, see Interrogating HTML tables with the Universal Web Adapter.
  • If you plan to run Robot Runtime in administrator mode, you must also run Edge in administrator mode. For example, if the target application that you are automating is running with elevated privileges, then you must run Robot Runtime with similar privileges. To ensure that Edge runs with elevated privileges, in the AdditionalArguments property of the Universal Web Adapter in Robot Studio, add the following parameter: --do-not-de-elevate.

The following additional considerations apply when you interrogate Microsoft Edge running in Internet Explorer (IE) compatibility mode. Microsoft designed Internet Explorer mode for situations where you need Internet Explorer 11 to retain compatibility with legacy websites and applications, but also need a modern browser for more modern websites and applications.

  • Interrogate and then stop each Edge adapter before you begin interrogating another Edge adapter. Attempting to interrogate two different Edge adapters simultaneously results in errors.
  • Stop all Edge processes before you interrogate IE compatibility-mode pages.
  • When you run an automation that contains a Universal Web Adapter with IE compatibility-mode pages, shut down all Edge processes before you start Robot Runtime.
  • The controls that you interrogate on an IE compatibility-mode page generate legacy web automation controls and match rules.
  • To have access to the properties, methods, and events of a frame or top-level Windows form in your automation, use non-global webpages.
  • When you use multiple Universal Web Adapters with Edge and IE compatibility-mode pages, ensure that the Edge configuration properties for each Edge adapter are the same.

Installing the extension

Use the Setup wizard for Robot Studio and Robot Runtime to install the Pega Edge extension. To update users from the command line, use the command line installation with the INST_Edge=1 parameter to install the extension.

If you install Robot Studio or Robot Runtime without the Pega Edge extension and later want to install the extension, use the web installer utility. This utility is located in the Robot Studio or Robot Runtime installation folder. The following is an example of the command you enter to install the extension and update the messaging host for Edge.

OpenSpan.WebExtensionInstaller.exe Edge -i
Note: For help information about additional parameters that you can include, append the -h parameter to the command.

Enabling the extension

After you install the Pega Edge extension, the first time any user starts Robot Runtime, that user must decide whether to enable or uninstall the Edge extension. Automation developers, of course, would enable the extension. Automation end users must enable the extension soRobot Runtime can automate the browser. If automation end users do not enable the extension, you must perform a manual process to recover and re-install the extension. For more information, contact Pega Support.

  • Using Microsoft Group Policy to control Edge policies

    If you use a Microsoft Group Policy Object (GPO) to control Edge policies, and you enable the Configure native messaging block list setting in the Native Messaging section to block all extensions, perform the following steps to provide Robot Studio and Robot Runtime with the access they need to function correctly.

  • Group policy setup for the Edge extension

    Explicitly allow the Edge extension in the Group Policy Editor to use the Edge extension when you create or run automations in the Microsoft Edge browser.
