This topic describes how to resolve the SmartBear Test Extension Is Not Installed or Is Disabled error. This error prevents web testing in TestExecute or TestExecute when you use Google Chrome or Microsoft Edge.

This error occurs because SmartBear Test Extension version 14 is no longer available in the Chrome Web Store. TestExecute and TestExecute require version 15.

Note:

SmartBear recommends removing all references to version 14 and configuring the browser to use version 15.
