Hi William, Is that the entirety of the error message that you are seeing? If you perform an embedded browser health check (via the Help -> Embedded browser health check menu option) then are any further details displayed (if it is easier to provide this type of information via screenshot then please feel free to email us at support@portswigger.net). Are you able to provide us with some further information about your environment - are you using Linux or Windows? If you are using Linux, are you logged in as the root user?

I was using Windows.

Hi William, I am aware that quite a substantial period of time has elapsed from the time that you raised this issue and your response to our initial questions - do you still require assistance with this problem?
