This functionality is supported only if you are using the Classic Agent.
If you are testing non-Web applications, you must disable browser extensions on your host machine. This is because the recovery system works differently when testing Web applications than when testing non-Web applications.
Furthermore, when you select one or both of the Internet Explorer (IE) extensions on the host machine’s Extension dialog box, Silk Test Classic automatically selects the correct version of the host machine’s IE application in the Runtime Options dialog box. If the target machine’s version of IE is not the same as the host machine’s, you must remember to change the target machine’s version.
