How to scan with WebInspect an application that uses Adobe Flash Player?

I am trying to scan an application using WebInspect Enterprise.  This is one that requires a logon macro because of our SSO system.  But when I try to record a logon macro using the WIE console tool, after login using the built-in Firefox rendering engine (browser) the app simply displays a message that it requires Adobe Flash Player version 10.3 or greater to be installed.   But this cannot be installed into the tool's rendering browser.  I tried using IE and it logs on correctly, but upon replay it never displays the logon page.  I have the same problem using the guided scan feature. 

Is there a way to make Adobe Flash Player available in the default 'browser'?
