Its explained in videos - how you can download and install Loadrunner.
Testing and simulating load upto 100 users is free in Loadrunner. You do not need any license for that.
So this feature makes it easy to learn and with 100 user limit, its more than enough to learn.
Yes we do help if you have project. But we also expect that you watch the videos and try to implement the project. If stuck in between then we can help you in the project. Help is available on our forum and skype.
