Fitnium and Internet Explorer

[Michael F-5]

Has anyone run Fitnium with Internet Explorer?

I'm using the latest build from Fitnium but when I try to get my scripts to run in IE, for coverage so we are not just running FireFox behind the scenes, I only get errors from Fitnesse.  I've used the following as browser values for Internet Explorer - iehta, iexplore, *iehta and *iexplore

Each time though I get a timeout and then:
java.lang.RuntimeException: Could not start Selenium session: Failed to start new browser session: Error while launching browser

Does anyone know if there is a value that works?

Thanks,

Michael
