Hi Sooraj,
Distribution rights are going to vary according to vendor and product. Is there a specific product you're referring to?
I know that in our own products we typically state these stipulations in the End User License Agreement, which is included both in a dialog in the installation, as well as in the Resources -> Documents section of the product on Acresso.com:
http://www.acresso.com/products/is/installshield-resources.htm(The short version is that the ability to redistribute certain components such as the InstallShield MSI tools and the Standalone build is limited to a small number of Build machines, and not end user machines).
Hope this helps!
