Cust Wiz ignoring option to Disable View In Browser

Question

I have set the CustWiz/MST to 'Disable and Lock' the ability to display PDFs in the browser.  We want them to open separately in Acrobat.  After I deploy, the setting IS disabled and locked, but when you click a PDF in the browser, it STILL opens in the browser, and not in Acrobat.
I am pushing Acrobat onto machines that already have Acrobat Standard 9 installed with the same settings.  It worked properly then.
What is causing this setting to be ignored?  How can I fix it?  It's delaying my deployment.
I have to deploy Acrobat 9 due to the bug I discovered here:

(With many other frustrating responses).
This is getting a little irritating...
Thanks for any input!

Thanks for chimming in:  So I guess in 10.x, the setting exists in two places?
First one is here:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\10.0\FeatureLockDown
and bBrowserIntegration is set to 0
And:
HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Adobe Acrobat\10.0\Installer\Migrate\_D9DD5E63-3959-464F-8E81-CF2ACBCE3BE9
bBrowserIntegration is a string where there is also a dword = 4.   (Does 4 = disable and lock?)
See screenshots
From what I can tell, it looks right....
