On Windows, Designer defaults to using Internet Explorer as the internal web
browser. However, Internet Explorer in Windows 10 or higher versions has
compatibility issues with the latest JavaScript libraries, leading to issues
while loading web pages in the internal web browser. For example, the internal
browser fails to load Integration Server Administration (http(s)://$host:$port).
This issue is resolved either by using an external web browser or updating the default
browser as Microsoft Edge in the config.ini file.
To set an external web browser in Designer preferences, do the following:
In Designer preferences, select General > Web Browser.
Select the “Use external web browser” check box. Click “Apply and close”.
To update the default internal browser, do the following:
Open $INSTALL_DIR\Designer\eclipse\configuration\config.ini in a text editor and
append the following:
org.eclipse.swt.browser.DefaultType=edge
Restart Designer. Then, reopen the internal browser view.
