I attached a video on this one. It shows what happened to me. IDK how to fix that. If I run fore installer 1.17.1 it does output something but so short time that I cannot even read anything and it just closes. I have tryed to use "java.exe" and "javaw.exe" and both just does the same. What is the reasoning of that. It pops out an command prompt looking windows for about a second but then closes constantly. I haveinstalled forge and its mods a lot befoure. This is my new PC so im doing the same thing again. I have java 8 now. I had java 16 and 11 befoure, but i thought that having 11, 8, and 16 at same time might glitch it. But the reason seems not to be so. So help me, since i dont really know what is the reasoning of that and how to fix it. I really need it.
