Long story shortened:
-
The x64 installer for the CRM 2011 Outlook client does not include everything necessary for the client to work.
-
You must download the x64 installer for SQL Compact 3.5.
-
You must upgrade the x64 version of SQL Compact 3.5 to version 3.5.8082.0 with the hotfix.
-
At this point the Outlook client should be able to connect to your CRM 2011 organization.
