Re : Problem upgrading to SDP Build 9001

It's probably down to not getting JRE 1.6 installed in build 9000.

D:\AdventNet\ServiceDesk\jre\bin>java.exe -version
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)

Note:

* PPM size will be 200 MB , because we have bundled PGSQL 9.2.4 & jre 1.6
