How can I lock a program to a computer so that it can't be copied off a computer? Is there a software solution available, or would it be better to try hardware, such as a dongle, etc. Any help is greatly appreciated.

It may surprise you to know that it isn't easy (in many cases impossible) to copy a program that's installed on a PC so it can be used on a different PC.
What needs to be safeguarded is the setup program, which is either on a CD or is saved on your hard disk. Without the original setup files (or an exact copy of them) the application in question cannot be installed elsewhere. when you install a Windows application, files are placed in several locations and entries are added to the Registry --- it's impossible to duplicate this by copying since you don't know where to look for all the support files without which the application will not run. Consequently, all you need to do is lock away the installation discs to prevent them being copied.
