Problem with start OpManager 10.0 on Windows 2008 R2

[Process]
1. install OpManager 10.0 on Windows 2008 R2
2. start the service
3. OpManager top page does not appear when accessing http://localhost:8060 (Port 8060 is not listening)
4. restart the service
5. same with 3.

...

then, problem occurs

Logs show "Unable to create database Exiting OpManager, Unable to start POSTGRESQL daemon".(*1)
I tried http://www.manageengine.com/network-monitoring/troubleshooting-guide.html#start3, but nothing changed.(*2)

Any idea?

(*2) bin/ReInitializeOpManager.bat that is should be on "http://www.manageengine.com/network-monitoring/troubleshooting-guide.html#start3"
not exist so I can't make bin/ReInitializeOpManager.bat run.
