I am working on a WiX based installer and would like to include DB2 9.5 driver installation as part of the MSI installer. However the IBM DB2 merge module is not passing the ICE validation test from ORCA, specific there are ICE errors on

* 03 Invalid Filename; Table: File ...
* 08 Component has duplicate GUID
* 10 The property 'ProductVersion' is not allowed in a Merge Module
* 30 Installation of component would cause file to be installed twice

I am using "IBM Data Server Driver for ODBC and CLI Merge Module.msm" from DB2 9.5 fix pack 4; Is there anyone that have experience using DB2 merge modules with WiX that might share a few pointers?
