Norton Internet Security can be too secure (!)

You can disable Download Intelligence temporarily for the time it takes to download the program.  Do not disable Norton Auto-Protect.

How to do this: In Norton go to Settings > Web > Download Intelligence > change to Off at top of page – Select Apply > select a time and OK.
