SSAS 2012 - AMO problem

[RegiRobert]

Hello,

Using the "IBM Cognos Executive Viewer" for definition of OLAP access (using MSAS) works fine.
I can create database definitions for every cube in my SSAS 2012 database.

However, when I try to connect to any of these cubses using teh "IBM Cognos Executive Client", I get this error:
"Invalid parameter
Additional information:
Loading/instantiating DSO/AMO server instance failed! "

I have installed AMO objects from the SQL Server 2012 feature pack (after installing "IBM Cognos" first).

Has anyone experienced this kind of problem?
Is the "IBM Cognos 9.5.1 EV" incompatible with SQL Server 2012?

Tia,
Regi Robert.
