But I have license to activate the toolkit and also i already did that.

Check your interface name

This error is generated when the IMAQ Init VI is called with an incorrect interface name. In MAX, the NI-IMAQ driver assigns an interface name to each IMAQ board in your computer, starting with img0, then img1, etc., in the order in which the boards are installed. If for example, MAX has img1 set for your interface and then in your code you call the IMAQ Init VI with the interface name img0, it will give you this error.
