I have both installed because not everything works running 64bit java, you do require 32bit java for some applications (Yes you can run both without an error.)
Operating system is windows 7.
The problem is, I launch the launcher and it says "Can't Find Java Directory"
Context (The circumstances that form the setting for an event) of problem: (Not even the right selection of problems) You probably meant, my debugging process? I didnt have one, what am I supposed to do, I have both installed, and verified that they both work by running applications using them.
There are no logs because the system isn't getting far enough to the best of my understanding.
My solution... Run minecraft on my crappy laptop running only java 32bit because it will only work if I only have one installed and I cant run uninstall 32bit or 64bit from my desktop because some of the applications that I use for work that were developed require either 32bit or 64bit (and yes I have tried to run the ones that require 32bit with just 64bit java installed and vice versa. They well not work, I need to have both installed.)
So no offense, I really hope this problem is resolved before Tekkit 2.0 because I really can live with playing minecraft on my crappy PC on SSP, but when playing online on my Tekkit server, it would really suck.
Sorry if this sounds rude, I was really tired and wrote it in a hurry. Please none of this was meant in a mean way. You guys are providing an excellent service and I wonderful complication of mods! I hope to keep using them, just gotta find a way to resolve having both 32bit java and 64bit java installed at the same time.... Maybe you guys can add an option to allow us to point to the java directory?
PS: Just so you know, in case you didnt get it from the message above, I did resolve this problem. I had to have either 32bit or 64bit not both. So if anyone is having this problem and you have both and do not need both, just uninstall both java versions and reinstall the one of them.
