You also can download the latest 11g version of AwM and simply choose
cube type 10g when connecting and logging into the database instance.
The 10g cube type of AwM 11g provides the exact same functionality as
the latest 10g version of AwM.
The readme for AWM 188.8.131.52 states that "It requires, at a minimum, a connection to Oracle OLAP 184.108.40.206.0 production software or later. In addition, the Oracle Database must be in 11.1 compatibility mode or later.".
Despite that, I have tried connecting to a 10g database with the latest AWM and it doesn't work... is there a trick?
