Java help

[xx]

Trying to install/run optifine. Whenever I try opening the .jar file, it opens cmd for a split second then it closes. Ive also tried running forge, so it's not an issue with optifine. Lots of people on different websites say theyve had the same issue but none of the fixes are working for me. Any help?

Try running manually with cmd.exe, so you can see any error messages.

java -jar <PATH>

Run the cmd.exe as administrator and try again.
Also, to avoid confusions, put the jar on your Desktop - then use

cd C:\Users\Shack\Desktop
java -jar OptiFine_1.14.4_HD_U_F2.jar
