If you are reinstalling a program from the Internet or doing a first-time install, should you choose the run instead of save option during the installation? For all installs over the Internet, I always encourage my clients to do saves instead of runs and I will go over a few points as to why this is best.
Need to install the software program on multiple computers? To reduce the killing of your bandwidth, save the software program to your portable media (such as a USB Flash Drive or CD/DVD) so that you can reinstall the software program to the other computers.
To download software programs, at times, licensing and download fees, are involved so if you have a copy saved locally, this prevents you from paying additional fees to download the software program once again.
By saving the software program to the computer before installing, you can then scan it with your antivirus program to see if it is safe before executing it as legitimate sites often get hacked by exploiters who can upload rogue files for you to download and install.
