Reader Security popup after X to XI upgrade - have tried customization wizard, reg edits, everything

Title: Adobe Reader Security

Body: Trusted certificates from your previous version of Adobe Reader were found.

Would you like to import them?

Any certificates that are not imported in this step will not be available in this version of Adobe Reader.

Buttons: [Import] [Use Default]

I've read through at least a dozen posts on many sites about this and no one has a real resolution.  Let me tell you what I've tried.  Each attempt was a clean upgrade from X to XI.

1 - First I tried the Customization Wizard, which did everything I want except get rid of this popup.

2 - Then again I went back in the Wizard and set the Directory Servers (C:\Users\myusername\AppData\Roaming\Adobe\Acrobat\11.0\Security\directories.acrodata) and Trusted Identities (C:\Users\myusername\AppData\Roaming\Adobe\Acrobat\11.0\Security\addressbook.acrodata) to copies of my own files on my own computer that did not get the post-install popup.

3 - I tried the same as #2, but with copies of my files from the C:\Users\myusername\AppData\Roaming\Adobe\Acrobat\10.0\Security\ folder (rather than version 11.

4 - I tried in the Wizard to add keys to HKCU\SOFTWARE\Adobe\Acrobat Reader\11.0\Security\cDigSig\cAdobeDownload for bAskBeforInstalling and bLoadSettingsFromURL both to 0.

5 - I tried on the cliet PC to change HKEY_USERS\clientusername\Software\Adobe\Acrobat Reader\10.0\Security\cPPKHandler\bCustomPrefsCreated to 0 prior to installation.

All of these still resulted in prompts to import the old certificates.  I'm out of ideas.
