When running Axe with HP UFT 11.5 for the first time you may experience errors on the Browser Basestate methods. This is UFT throwing a 'General run error' on the Browser.Navigate method. The error is because UFT requires an Internet Explorer add-in from HP called 'BHO Manager' to be enabled. This was not required with earlier versions of QTP. More information can be found on the HP Support Forum here.
The screen shot below is an example of the problem:
There are two ways to enable the BHO Manager Class browser Add-In:
1. Respond to the prompt when Internet Explorer is started for the first time on a machine with UFT installed.
Press the Enable button.
2. Enable the Add-In from the IE tools menu.
Select Tools -> Manage add-ons.
Highlight 'BHOManager Class' and click the Enable button.
