Internet Explorer support

Updated on October 19, 2022

Interrogate and automate applications that run on the 32- and 64-bit Microsoft Internet Explorer browser, versions 11 and later.

The ability to automate applications that run on Internet Explorer is included in the Web adapter.

Note: For the latest news about Internet Explorer, be sure to watch this Pega Community Events webinar: Microsoft is changing the browser game - Are you ready? For specific version information, see the Application Support Matrix.

Consider the following additional points.

  • When you use version 11 with Siebel, enable the Compatibility View feature in the browser. Compatibility View helps websites that are designed for earlier versions of Internet Explorer to display correctly. This functionality can affect Robot Studio matching.
  • To handle embedded .NET applications, set the correct permissions. Otherwise, attempts to load the Robot Studio .NET translator inside Internet Explorer either function incorrectly or cause Internet Explorer to crash or hang. To avoid this problem, the .NET translator is not loaded into Internet Explorer even when the .NET runtime is detected. Because of this, Robot Studio treats the controls inside of the .NET application as regular Window controls.
  • Pega Robotic Automation does not support the TabProcGrowth registry entry. This setting limits the number of tabs that Internet Explorer can open on a single process.
  • Pega Robotic Automation supports Protection Mode in Internet Explorer, but does not support Enhanced Protection Mode (EPM), which is available in Internet Explorer 11 and later. Disable Enhanced Protection Mode in Internet Explorer advanced security settings when you develop automations.
