Acrobat 8 + Outlook on Windows 7

I installed MS Office Suite 2007 on a Windows 7 machine and then installed Acrobat 8 Pro. None of the PDF Maker plugin/add-in menu options appear in any of the Office applications, including Outlook.

I've installed Acrobat 8 on XP + Office 2007 and Vista + Office 2007 combinations and always the PDF Maker toolbars and right-click menu options have appeared in the Office apps without any problems.

I've tried uninstalling and reinstalling Acrobat 8. That didn't work. I've tried going in to "modify" the Acrobat 8 installation in order to make sure hte PDF Maker macros are installed for the Office apps and they are. I've looked through the "Customize" options for menus and toolbars in the Office apps and there is no sign of PDF Maker or Acrobat there. I've looked through the preferences in Acrobat for something to turn-on and the "Options" in Outlook but haven't found anything.

Is Windows 7 blocking the PDF Maker macro or something? Has anybody else had this problem? Am I missing something obvious?

Thanks for any help you can provide!
