64bitMAPIBroker.exe - system error on Reader XI

Question

Hello,
I have a PDF form that uses event.target.Maildoc in the XML source to generate an email message when the button in the form is pressed. We all use Microsoft Outlook as our mail clients and those users that have had 64 bit Office installed have not been able to use the button as intended because previous versions of Acrobat/Reader could not communicate with the 64bit MAPI, this is not new and this is not the reason for this posting.
I have just tried my PDF form with the Mail button on a fresh install and fully up-to-date test machine which is a Win 7 64 bit system with Office 2010 x64 and Reader XI and have gotten the below error after answering which mail client I would like to use in the box that pops up when I press the mail button.
My understanding was Reader/Acrobat XI were supposed to be able to handle 64bit MAPI calls.

Answer 1

At least on my test system Reader did not even installl the 32 bit version.
edit: Though in the case of this test system I used the small Reader exe installer from adobe website, whereas I normally use the MSI installers from the adobe FTP. So maybe that makes a difference.
