Need help with running a .Bat

[Gamer_T]

Hi guys.

I'm trying to run a .Bat file and when I run it, it just comes up with a black screen and goes off.

The files are compiled correctly etc as they're working for lots of other people.

If I remember correctly, last time it was because I was on a windows 64-Bit Operating system and I had to add some command line to something in Windows but I can't remember what I did.

Anyone know what I need to do? :/

Thanks

I remember what I had to do now.... I had to go to system variables and change a classpath or something but I can't remember exactly what it was.
