Went to that link (every single time I have downloaded Flash today, actually, which has now totaled at least 10 times); unchecked the McAfee option; clicked the "Download now" button. As a sidenote, a paragraph above the button says "By clicking the Download now button, you acknowledge that you have read and agree to the Adobe Software Licensing Agreement and the McAfee Security Scan Plus License Agreement." (This will be important in Step 3 of your instructions.) Back to the bolded material from your step - your instructions say to save it to my desktop. The dialog box does not offer me the option of selecting a location to save the file - it just asks me whether I want to save it at all. I choose yes; it automatically saves it to my Downloads folder, which can be found by going to C:\Users\\Downloads. Just for shits and giggles though, I went ahead and right-clicked on the file from my Downloads window that pops up in Firefox, selected "Open Containing Folder" and copied the installation file to my desktop - just to make sure that the location from which I ran the file didn't have something to do with it not working for me previously. I know I'm getting ahead of your steps here, but it seems relevant to note now that the results were the same when I copied and pasted the file to my desktop.
