I launch the start.bat file by just clicking on it in the folder and it just crashes. Which from my research is all I thought I had to do. I was running it as "Run As Admin" thinking that'd work, but it clearly does not.
NOTE: I've installed the proper 64bit version of Java now: jre-8u221-windows-x64.exe. So the path name will be a bit different.
Not sure what you mean by running it from the command line, so below are a few things I've tried based on my knowledge and guessing.
1.) Copying and pasting the whole line of code into the cmd.... Result: "Error: Could not find or load main java class.... (I haven't seen this error before so it's new for me) See Capture
2.) Changing directory.... Same error, capture 2
3.) Removing "C:\Program Files\Java\jre1.8.0_221\bin\java.exe" from the beginning... Result: Now it worked! Capture 3. ALSO, I got the same result by just clicking on the start.bat from the folder.
The only reason I added the path "C:\Program Files\Java\jre1.8.0_221\bin\java.exe" is because I thought that's what I had to do. I saw it in the description of this video: youtube.com/watch?v=3W8Di4I2usE&t=2s.
