The first link worked thank you so much!

Heres the full crash report, Forge 1.12.2 works fine without Optifine, but as soon as I try and launch with it it crashes after seemingly almost loading.

Heres some screenshots

It's called "Server (2)"

I get this instead when I run the official minecraft one

C:\Users\Chris Kim\Desktop\server 2>java -Xmx1024M -Xms1024M -jar minecraft_server.1.16.2.jar
Error: Unable to access jarfile minecraft_server.1.16.2.jar

C:\Users\Chris Kim\Desktop\server 2>PAUSE
Press any key to continue . . .

I got it from the official minecraft website https://www.minecraft.net/en-us/download/server

I downloaded the latest 1.16 version of the java minecraft server, then put the jar file into a server folder. Once that was done I ran it, changed the EULA to true, then I created a batch file to run the server. But everytime I try to start it I get this.

C:\Users\Chris Kim\Desktop\server 2>java -Xms2048 -Xmx2048M -exe Minecraft_Server.exe -o true
Unrecognized option: -exe
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Does anybody know how to fix this?
