On Solaris 32-bit platforms, add $TIBCO_HOME/clients/c/lib to LD_LIBRARY_PATH
On Solaris 64-bit platforms add to following to LD_LIBRARY_PATH:
$TIBCO_HOME/clients/c/lib/64
$TIBCO_HOME/clients/c/lib
On Linux 32-bit platforms add $TIBCO_HOME/clients/c/lib to LD_LIBRARY_PATH.
On Windows 32-bit platforms add %TIBCO_HOME%\clients\c\bin to PATH.
On HP-UX 64-bit platforms add the following to LD_LIBRARY_PATH:
$TIBCO_HOME/clients/c/lib/64
$TIBCO_HOME/clients/c/lib
On IBM AIX 64-bit platforms add the following to LIBPATH:
$TIBCO_HOME/clients/c/lib/64
$TIBCO_HOME/clients/c/lib
