I downloaded Visio, but it does not appear anywhere in my system.  In the Downloads folder is a prompt to burn it to a disc.  I plead ignorance with computers, but 1) where is the download, and 2) why would I need to burn it to a disc?

because the download is a diskimage (thus the img file type). The choices are burn to a disk or right click it and 'mount' it.

I truly appreciate the response.  Don't laugh... what does 'mount' mean?

If you are using Win7 (8) when you 'mount' an IMG file the operating system creates a virtual cdrom drive and then loads the disk image into it. If open the computer icon you will see that you now have a new drive and the disk is loaded into it.
