(1)Application:- It is a web based application which works on IE

(a)For load testing if i use load runner is it compatible with QTP
(b)Can i have as many Vusers as required using QTP scripts in load runner , what is the procedure if possible
(c)In QTP the scripts perform operations by opening a browser but if i perform load testing then n number of browser will get open and will degrade the system performance and may be can hamper execution, so what is the procedure of making the browser inactive in QTP scripts as we can do in VuGen
(d)What are the requirements for using QTP and load runner together.. License part ??

I am new in this , will be really glad if i can get some help

Thanks and Regards
