Siebel 8.1.1.8 patch OUI installer issue in windows server

We are trying to install 8.1.1.8 patch on 8.1.1.3. After clicking on setup.bat, installer is not launching, so we are not able to start the patching.

please find the server details as below:

Microsoft windows 2003 Enterprise Edition service Pack 2
RAM - 6GB

Same installer is working on other server.

When we tried to launch installer in debug we got Java exception. Though Java version is correct (and same when compared to working server)
