Like MaksiSanctum, I had to install Reader 8.2 in order to get Reader to work under W7Pro. To get to R8.2, I had to tell the Adobe downloader that I was running an other system. It then gave me the option to check XP SP3, and this gave me the option to select R8.2.
For better or worse, I also turned off all of the Norton anti-ware prior to making this attempt. Yes, folks, I changed multiple variables at once, so I cannot be sure which action actually was the effective one.
