So for a while now I have been trying to install the latest version of forge. I have everything correct to using the right version and using Java(TM) Platform SE binary. But for some reason when I try to open the installer the blue loading circle pops up and goes away without even opening a window. I've deleted the file restarted my computer and reinstalled but the same things happens over and over again. I've tried doing this on two different computers now but the same problem arises and still it refuses to open the installer file. Somebody please help me. :(

Try running the installer from the commandline, and if it fails post the output here.

I opened the command prompt and typed "cd downloads" and when I tried opening the forge file by typing "cd forge-1.15.2-31.1.34-installer.jar" which is the exact name of the file it said "The directory name is invalid" What should I do from there?

After you're in downloads, type "dir forge*" (there's a * with no spaces after forge) to make sure it's there. If it is, you want to use

java -jar forge-1.15.2-31.1.34-installer.jar

 

cd means "change directory", that's why you got an error trying to cd into the installer.

I followed your commands and it finally opened. Thank you so much, you are a life saver
