i cant start an instance, it comes out saying that the java path could not be found, what do i do.

mind you that I have just updated java to java 8

[02JanDal]

Go to settings, select Java on the left hand side, and choose "Auto-detect", and then select the new Java

when I did that, it came up with just the word: java

[02JanDal]

Select it, click Ok, and then try launching the instance again

I have just done this, and when it crashed mid launch it didn't even give me a crash report

[02JanDal]

You're aware that you waited 2 minutes? And that we're just as much humans as you are?

what should I do next

ya I know, i'm just in a frustrated mood this morning, sorry

would giving you all the mods i ues in my instance help you?

[peterix]

No.

Did you reboot/relog after changing the java install? Maybe that could help.

You can also set the java binary manually (there's a browse button for it). Just look for javaw.exe

i have on the first one, and il try the second one

i cant find the rite thing within the java bin, and there's about 82 different options, what is the specific name that i need?

[02JanDal]

javaw.exe or java.exe

ok, thanks, il try that

i tried both of those, and i get the same crash without a report mid launch

[02JanDal]

Go into the settings and find the one for keeping the log window open

ok, i have a log now, here is what i got for the javaw.exe:
