How do you Fix a Java Error when the command prompt flashes and disappears?

So, on my old computer I was able to download the same file I am trying to get now, but my new computer has trouble with that file. (I am using a x64 bit Windows 10)
This is what happens:
I download the (safe) .jar file from OptiFine.net (minecraft Mod)
I (attempt) to open it the same way I used to. (double-clicking)
Nothing happens so I take the long route, I right click it > Open With > Choose Another App > Look for Another App on This PC > Java > jre1.8.0_131 > bin > Select the First Java That comes up (simply just says java)
After I do that, there is a quick flash. On the flash it is a black box, and it looks much like the command prompt.
I have tried downloading other java files and such but I have the same result. Any ideas how to fix?

List the steps to add a shortcut to your Windows desktop to access a command prompt window?
There is technically no specific way to do what you are asking here...If an application is DOS based, then it does not need a shortcut to be started through command prompt, you can just create a shortcut to the executable itself, and it will automatically run in a DOS environment.You can't really create a shortcut to Command Prompt as you will probably get some System32 error on Windows. Butt you can create a batch file (.bat)Open up NotepadType "command.com" (Without Quates)The File -> Save AsName it as anything, I usually name it "CMD"Then add ".bat"Under "Save As Type" drop the box down and select "All Files"Then you can run Command PromptOr you could just drag and drop Command Prompt from the Start Menu to the Desktop.

How do you become an administrator using command prompt?
i have yet to figure out how to do it in command prompt, but you can do it in notepad... just copy and paste this code@echo offnet user USERNAME PASSWORD /addgoto admin:adminnet localgroup administrators USERNAME /addpausewhere username and password are enter your desired username and password, not your normal account, because this code will add a NEW user to log in as, and from this admin file, you can grant yourself admin access, that is, if your admin hasn't blocked that command so that you get "system error 5, access denied"

If you have a CD to restore the operating system it's a right time to use it. It looks like your PC registry was damaged which is incurable or some of system files were damaged to deleted. In the second case the restoring CD will help. Boot from the CD in the restore mode (command line mode) and try to restore the system.
