How about using the VERSIONINFO from oci.dll?

I still do not understand your statement, Anthony, that cx_Oracle is linked to a specific version of Oracle client.  I can use the same cx_Oracle with 10g and 8.1.7 by changing the PATH.  There are three components with "version" states.  If cx_Oracle executable does a static link to one version of the Oracle client library, then how can I use the same cx_Oracle to connect with both 8.1.7 and 10g?
