Cause:
======
Local CLASSPATH environment variable includes an incompatible XML Parser which has been used/loaded by TIBCO Universal Installer.

Resolution:
========
Unset the CLASSPATH environment variable before starting the Installer.

On Unix (terminal):
--------------------------------------------------
unset CLASSPATH
./TIBCOUniversalInstaller-&ltversion>.bin
--------------------------------------------------

On Windows (open a command window (cmd), and reset the CLASSPATH before start the TIBCO Universal Installer in the command window):
--------------------------------------------------
set CLASSPATH=""
TIBCOUniversalInstaller-&ltversion>.bin
--------------------------------------------------
