Unexpected error occurred during model generation

I am working with a client who has installed SQL Server 2005 Enterprise
on a Itanium 2 64-bit, 8 Gb ram. Normally when we install Reporting
Service their is no problem but when we did it on a Itanium we can’t
get it to work properly. When we are trying to generate a model we get
this error:

An error occurred while generating model. (rsModelGenerationError) Get
Online Help An error occurred during the generation of semantic model :
[Create roles from measure group dimensions]Unexpected error occurred
during model generation.. [Create roles from measure group
dimensions]Unexpected error occurred during model generation.
Unexpected error occurred during model generation.

"Get Online Help" link:

The "Get Online Help" quote is a link to Microsoft help service but
their is no help.
The client is desperate to get a solution to this problem. What other
information do you need to help me find a solution

Hope someone can help

I have come across this with one of our servers, you need to be a db admin to be able to generate the model.

This is something i have been told MS are addressing..
