When installing ECC on a Windows server, the JDK install has to happen before you begin. There are two Environment Variables that must be set in order for the install complete. I always run into this, but now is the first time I thought to go ahead and put an entry in here about it.
JAVA_HOME and SAPINST_JRE_HOME both need to be set, pointing to the Java install directory, most commonly C:\j2sdk1.4.2***
Hope this helps things go a little smoother for you guys.
