    Question how do i open a .jar file with a run.bat script

    So im trying to open a .jar file called optifine with a run.bat by using the following code in windows 11

    start javaw -OptiFine_1.19.2_HD_U_H9 (1).jar

    but after that it responds with an error of:

    Error: could not create the java virtual machine.
    Error: A fatal exeption has occured. program will exit.

    how do i manage it so that i can open the .jar file with a .bat code . or just open it in any way and also future .jar files that may come up

    I just downloaded the latest version of java too, deleted it and downloaded it back up again, and reset my laptop multiple times, yet i cant manage to open the .jar file, i just need some answers

    What happens if you enter the command: java -version in a command prompt window?
    Why are you trying to use javaw instead of java?

    Note: the java commandline option to use a jar file is: -jar
    java -jar TheJarFilename.jar
    If you don't understand my answer, don't ignore it, ask a question.
