I think that doc is slightly off . . . I'll look into the details for you.
A quick review of the addon display behavior in IE on various machines shows the following:
- Adobe PDF Reader may or may not appear in IE's Manage Add Ons panel by default. Why is a mystery to me, but this is also true for some non-Adobe products so it's probably some IE setting.
- In the Show drop down list, choose another display option. The Adobe PDF Reader entry shows when I select "Run without permission."
- You can enable/disable the add on by choosing a Display option in which Adobe PDF Reader appears.
Hmm... I feel kind of stupid now , why didn't I check "run without permission". Thanks brogers, this answers my question!
Funny how "AcroPDF.dll" manages to "hide", I even tried to track it down using Sysinternals AutoRuns and Process Explorer without finding a trace but it never occured to me to check "run without.."
