IE9 - Stop pdf's from opening embedded in the browser

win7, IE9, adobe reader XI. In order to stop ie from opening pdf's embedded in the browser, I need to disable the ie 'adobe pdf reader' add-on. I need to do this on a thousand machines so I can't do it manually. I've tried doing it via group policy using the below link, but it didn't work. The add-on said it was disabled, but pdf's still open embedded. Can anyone tell me how I can do this programatically, via group policy or via registry etc?

Adobe offers an administrative template for GPO for Adobe Reader 11.
This allows to modify the option 'display pdf in browser'.

Alternatively you can set registry value bBrowserIntegration in
SOFTWARE\Policies\Adobe\Adobe Acrobat\11.0\FeatureLockdown.

However because this doesn't work for all browsers, Adobe recommends

odd. I tried using their template and disabling 'display pdf in browser', but it didn't work. I can even still switch it back and forth manually. I can see that the policy was applied as the below registry value is there. This is giving me a headache. Maybe this policy was originally made when that setting was a setting in adobe, and not an add-on in IE. But it specifically says it's an adboe reader XI template.
