Installation

How can I quickly install a new license file?
When I try to install HVE, the process is stalling just before it starts copying files to the computer.
When I start my HVE or HVE-2D program, I see a message that indcates a license file was not found and I am running in Demo Mode. I am sure I have a license. Why am I getting this message?
How do I properly install HVE on my computer?
