Could not find main class
i know next to nothing about java ,basically nothing. Im using windows 7 premium,no viruses,malware or anything. I play a game called minecraft wich uses java. I am trying to use this [JAR] TFCs Mod Manager [UPDATE 14.1] Check mods updates! - Minecraft Forums when i download it it downloads in a rar format,i then have it put on my desktop. Well the instructions say to run the program with javaw.exe , I figured out how to select the javaw.exe . So now the file is displayed as a page with the java logo instead of the stack of books . When i double click to run it i keep getting" could not find main class,its like this for every program i download. I have been on google searching high and low for a fix. Ive uninstalled ,reinstalled,rebooted,registry cleaner.etc..... NOTHING HAS WORKED.Java's website just says to reinstall.wich ive done 5 times today lol.
