I tried running the launch batch file and all I got was C:\Users\(myname)\tekkit server>java -Xms3g -Xms2g -jar Tekkit.jar nogui 'Java' is not recognized as an internal or external command, operable program or batch file. C:/users/(myname)/desktop/tekk­­it>pause press any key to continue... I tried changing -Xms3g -Xms2g to -Xms1g -Xms1g but that didn't help, what do I have to do to fix this?
