32-bit DSN doesn't show for vUM install

Trying to install vUM on a (virtual) Server - W2k8r1 sp1

separate from the vCenter 5.0 server.

I have more than 5 hosts and 50 guests (no local sql express)

Used odbcad32.exe to create System DSN using SQL driver v6.01.7601.17514 file name SQLSRV32.DLL. ...twice...

SQL authentication, connectivity test was successful.

When I get to the point of selecting the DSN to use to connect to a remote SQL database, nothing shows in the drop down.

Most of the search hits I get are about version 4 or commenting about the 32-bit driver.

Any hints?

Thanks
