No. My problem is with IDEA it's self. I installed it. But now it won't start up. Help?

That is quite strange. Can you try to run idea from the command prompt and see if any errors appear?

I didn't know you could run programs that way. I guess it makes sense. Nope, no errors. It simply comes on and disappears. Here is what it says:

I wonder what would happen if I re installed it.

Now that I think of it I did have to mess with ItelliJ's files a bit to get it to work. It was doing something funny where in its directory it would have something like /jre/jre/ and it would throw errors because it wanted a jre to be in /jre/. So I copied the files that were in /jre/jre/ to /jre/ and it worked. It had some sort of installation issues. Could that be the issue?

Yes, it might make IDEA unable to find Java at all, though I would imagine that some error would have popped up. Re-installing is a good try. And if the jre location is messed up, don't move the folder around. Change the configuration inside IDEA that points to the jre. Actually, you should probably have it pointing to a JDK, not the JRE.

Huh, I'll try re installing. But it is weird, when I tried to import my project the first time it said something like "I couldn't find a java.exe at this path..." Then it said a directory that said the directory of intelliJ and bin/jre/. Then i looked in the directory it said and there indeed wasn't a java.exe there. Instead it had two jre folders like: /jre/jre. It was weird. But when I copied the directory over to where it should have been, it worked once.

Oh and how will I change the configuration if the program doesn't even come up for more then 2.5 miliseconds?

Well, re installation worked, but I'm not sure if it will hold up when I close it and bring it back up.

 

Edit: Uhh.. It did the same thing again where it doesn't know where the jre is. It says, "The supplied javaHome seems to be invalid. I can't find the java executable. Tried location: D:\IntelliJ IDEA\IntelliJ IDEA Community Edition 14.0.3\jre\bin\java.exe". So i don't know. What should I do? You probably know more about Intellij IDEA than me.

About IDEA yes, but I don't use Windows =(

Do you have your JAVA_HOME environment variable configured? If so, what is it pointing at?

Ya, I configured it because Minecraft wasn't running a year ago when I installed jre 8. So, ya.

JAVA_HOME | C:\Program Files\Java\jre8

So that seems to be your problem. It is pointing to a JRE, instead of the JDK.

Ok, I changed it, it seems to be working fine now. Thanks. If I have any further problems, I'll make a new thread.

Oh and btw, I think I'm getting used to IntelliJ.
