When starting the launcher it appears to try to read all the installed versions of java, I do not use the java installer; I just keep the executables in folders. Therefore, there is nothing to be read, so it throws a npe and crashes. Previous versions of the launcher worked without this issue. It is nice that you added this feature

, but the launcher should work even when the java info isn't available.
It also seems to report that I am running "x86 Windows 8 6.2", when using 64-bit Windows 8.1, and running 32-bit java. Using 64-bit java correctly reports amd64. I also feel like it should say whether the version of java running is 32 or 64 bit when it says what version java is.

There also seems to be issues starting the game when using 32-bit java, numerous threads have been posted about this issue in tech support.

It's very strange, I can take the individual mods and add them myself to a 1.6.4 profile in the default Minecraft launcher, and it'll run just fine. It only seems to crash Java when done through the FTB Launcher.

The Minecraft Log had just two lines in it:
"Error occurred during initialization of VM
Could not reserve enough space for object heap"

Not having enough space is extra strange, because I was playing the 1.6.4 packs just earlier today.

I am unable to test this as the launcher is working for me, not sure if this is an issue on other oses, or when using 32-bit java on 64-bit windows.

The differences with 64-bit java are the same for both the command prompt and launcher console output.

Hope this helps
