ODBC 7.3.0.200: MergeModule problems.

I've encountered some problems with the distributed merge module when using
it in a deployment project made in MS Developer Studio .NET.

1) The module has no SystemFolder Directory defined.

2) Double defined file references?
------ Starting pre-build validation for project 'MSI' ------
------ Pre-build validation for project 'MSI' completed ------
------ Rebuild All started: Project: MSI, Configuration: Debug ------

Building file '....msi'...
WARNING: Two or more objects have the same target location

WARNING: Two or more objects have the same target location
('[systemfolder]\psqlodbc25.dll')
WARNING: Two or more objects have the same target location
('[systemfolder]\psqlodbc25.dll')

3) After fixing the above problems with Orca (MSI/MSM editor by MS) I get
the following error dialog when trying to run the MSI that includes the MSM:
"Error installing ODBC driver: PostgreSQL, ODBC error 13: Could not load the
setup or translator library. Verify that the file PostgreSQL exists and that
you can access it."

Any help would be greatly apreciated,
Thomas.
