I have Minecraft 1.15.2. I downloaded the appropriate forge version and made sure my Java is up-to-date. Every time I launch the installer all that happens is a window pops up, there is black in the screen, and then closes. Please let me know what I am doing wrong. Thank you for your time.

Try running the installer from the commandline, and see what it outputs.

May I ask for specifics. I am relatively new to this. Thank you for the reply.

If you are running windows, open the folder the installer is in, right-click on a blank spot and choose open command (or powershell) window.

then in that window, type java -jar <filename> and press enter.

So if the file I downloaded was forge-1.15.2-31.1.37-installer.jar it would be

java -jar forge-1.15.2-31.1.37-installer.jar

 

If it fails, type java -version

and paste the output here.

So when I went for the blank spot it did not have the option to open command. however I did get the command prompt to open and I followed your instructions. It failed.

here is the results of your second request

 

java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) Client VM (build 25.241-b07, mixed mode)

The good news is you have Java 8, so once you get there the installer should run. I do notice you have the 32-bit version, hopefully it won't matter for running the installer.

I am guessing that you may not be in the correct directory (folder) when executing the command.

Ctrl+M in the command window will let you mark stuff to copy (press Enter after marking it), and then you can paste what your command prompt window looks like here.

Show your attempt at running the installer, and then after also show the results of typing dir at the command prompt.

Where did you save forge installer jar? You have to CD into that folder.

It went into my downloads folder

Ok, that's good, since your downloads folder is right there.

cd Downloads

typing the above command will move you into the downloads folder, it should change the prompt to say

C:\Users\cooks\Downloads>

Then you can try typing the java -jar forge<TAB> again.

Thank you that seems to have worked. I appreciate your time.
