I recently got a new computer that I use only for my different software. I do not allow the pc onto the internet so it does not get any viruses. I downloaded autocad, inventor, and revit on a computer that does use the internet. I saved the files onto a flash drive to transport to my other computer. When I downloaded everything I did not allow the program to run. When I brought the files over they wont run what can I do to install these onto my computer I have the serial numbers.
Welcome to the community.
The installation requires additional files to be downloaded during the time of installation - especially Revit.
You will not get any viruses by connecting your computer to download the files during installation. You're being a tad bit too cautious here.
You can always use the Open DNS family shield DNS to block spam, virus, and malware sites.
