LoadRunner doesn't launch the IE browser

I am using Lr 9.1 and using the web/http protocol when I try to record any script it should launch the web browser with the url that I provided in the "Start Recording" dialog box. But it doesn't. When there is a another IE window open then it opens another Browser with the given url but still doesn't record any script. Please provide me with the solution to this matter.

Thanks,
Awal
