Thank you for your reply
I had prior to making this post located and tried this same page last night; however, when I tried the Illustrator CS3 "File 1" link it comes back with a 404 as follows:
HTTP ERROR: 404 /support/downloads/dlm/main.jsp
Follow the very important instruction mentioned on the page .
For others like me, the very important instructions are on the ProDesignTools page near the top. After following those instructions the download works even with my security software running.
