No Adobe PDF add-on in IE 8/9 after deployment

I beg your pardon if this "after deployment" question is posted in the wrong forum.
I really need some help with this one.. What am I missing here?


In Acrobat Pro 11.0.01 you configure display PDF in browser (yes/no) by enabling or disabling a add-on in the browser. I want my end users to be able to select how they wish to view PDF:s. According to ml there should be a add-on called "Adobe PDF Reader".


This add-on is missing on all my deployments so far!


For troubleshooting purposes I have replicated my problems when I install the product from original media without my transform and the results are the same. Am I missing some setting in the Customization Toolkit Wizard in order for the add-on to be installed properly?

On two completely clean and fully patched machines (XP x86 and Win 7 x64, english OS) I install Acrobat Pro 11.0 (english) and apply 11.0.01 patch.
In IE I select Tools -> Manage add-ons -> Show: All add-ons.


Adobe Acrobat Create PDF from Selection
Adobe Acrobat Create PDF Toolbar Helper
Adobe PDF Link Helper
Adobe Acrobat Create PDF Toolbar

There is no "Adobe PDF Reader", yet PDF:s are displayed in IE.

If I disable the four add-ons above, PDF is still displayed in IE.
If I launch IE in safe mode without add-ons ("C:\Program Files (x86)\Internet Explorer\iexplore.exe"  -extoff), PDF is still displayed in IE.
I terminate all visible Adobe processes (Acrotray, ARM for instance), PDF is still displayed inline in IE.


C:\Program Files (x86)\Common Files\Adobe\Acrobat\ActiveX\AcroPDF.dll is installed, if I rename this dll (using a SYSTEM account) PDF is displayed in Acrobat Pro XI.


How do I/end users control if PDF are to be displayed inline in IE or not *after deployment*??


(In Firefox everything works as expected and I can enable or disable the Adobe Acrobat plugin to control how PDF:s are displayed)

    Hi hh-hh,


    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.
