You don't have to change path in bat file. Actually, every java update uses new name, so you would have to change it every time. Just copy java.exe to tracker folder, but make sure you are using 32 bit version.
I just got new computer, installed java 32 bit, and copied tracker folder from old computer. All works right away.
Oh, and there are some problems with memory management, you have to use NoMap bat, after database grows too large.
What do you mean java.exe inqistor? the exe file from the main java folder in Programme Files?
I am having to reset database every 5 turns as thats the largest number of turns it can cope with
Yes, java.exe from java installation folder. I tried to enlarge memory available for tracker, but it didn't help. But NoMap file works fine. You need 32 bit java though.
