I have a jar file which used to work in Win XP, but doesn't in Win 7. I get a message "Could not find main class: C:\users\<file path>. Program will exit."
I don't really understand jar files, but looking around the main solution seems to be the need for a 'manifest file'...which doesn't help me because a manifest file already exists and appears to define the main class.
Does anyone have any ideas?
(I did think about Win XP mode, but my Win 7 is a personal edition)
