Hi,
please can anybody help to open an exe file,when I click to open it,it returns the message "unable to access jarfile ./bin/examengine.jar"

It's most likely trying to load a JAR file, in the bin folder relative to the location of the EXE. So if you have the examengine.jar file, you should put it in a bin folder, which should be in the same directory as the EXE.
