Thanks I already tried that.  I cleared everything in Firefox including cookies, cache, etc. I changed the name of the old file, and I tried downloading it again.  The file size was exactly the same as the previous downloads and unfortunately still does not want to run.

But I did discover something interesting though.  The other files that I have recently downloaded that did work are newer products with file names like "13141_B2BasicsJane.exe".  It is only the two older products with the old naming system like "ps_ac1826_productname.exe" are the ones that are NOT working.
