HP SIM software license

Hi Team,

We want to test latest HP VCEM SDK with our code.

I have downloaded latest HP SIM integrated version(with VCEM plugin) from HP site.

Do i need any software license to start the server and work with VCEM ?.

Also I have SIM 7.1 integrated installation in my machine . How can i get the software license ?.

I can use this old software license with my fresh 7.4 installation.

Kindly help on this.

Thanks,

Madhav
