It would be helpful to know which API it uses to access Oracle.

Normally ORACLE_HOME should *not* be set in an Instant Client installation.

If you are willing to try hard, you could install Process Monitor (http://download.sysinternals.com/Files/ProcessMonitor.zip) and trace which files and registry keys the program tries to read and write. There will probably be some Oracle related things that it cannot find. From that you could guess what it is trying to do.

But they might know which API they used, or how they check if Oracle Client is installed.
