Microsoft: Please make your launcher friendly for the modding community.

*Okay, for anyone else that finds this.*

The FTB launcher and Microsoft's launcher do not get along. If this happens, launch the minecraft launcher from `~/.minecraft/launcher/minecraft-launcher` standalone. It runs some update that, for some reason only known to cause player frustration, that never used to happen, doesn't work when it is launched from the FTBApp.

Then, exit that launcher, and go back to the one that FTBA launches. Then sacrifice several chickens to the Microsoft Wealth Gods, and maybe it'll work. It did for me.

So our workaround is this: https://github.com/Fenixin/Minecraft-Region-Fixer

Obviously this requires access to the server, but it has saved us from stupid amounts of entities.

Just to note, I can't right click on it any longer. It used to work, but I can't run that old launcher any more, it just tells me that I need to update.

My desktop is on Fedora 18, and running Oracle Java 7, it's a bit older:

$ java -version
java version "1.7.0_10"
Java(TM) SE Runtime Environment (build 1.7.0_10-b18)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)
$ cat /etc/fedora-release 
Fedora release 18 (Spherical Cow)

Same behavior happens on my ArchLinux laptop:

java version "1.7.0_40"
OpenJDK Runtime Environment (IcedTea 2.4.0) (ArchLinux build 7.u40_2.4.0-1-x86_64)
OpenJDK 64-Bit Server VM (build 24.0-b40, mixed mode)

It used to work for me in linux, prior to the latest version.

I did search for "create profiles" (without quotes), and it didn't find anything about creating profiles 😛

This is resolved with the new Dev Launcher. The old launcher still borks.

Grum: that is scary awesome!

Wait, now suddenly restarting the launcher works! Was that pushed out just a few seconds ago or something! Well done!

Restarting the launcher did not rectify this issue for me. I tried that.

It would be really nice if this were fixed, however. I'm behind some sort of evil proxy magic that I have no control over. There's nothing I can do about it, and so I cannot update minecraft due to a very ugly looking "Error: null"

I was pretty confident a null pointer exception isn't a support request.

It seems to work just fine at home, so I'm going to say that this is an isolated network issue that's happening at my current location 😞

I'll leave it up to the mojang devs if they want to have a nicer error than (4) null

Sadly, none of that works:

$ mv ~/.minecraft ~/.minecraft-old
$ cd MyStuff/
$ ./minecraft
asdf

@Ezekiel Elin:

There is no "Library" directory in my home folder, I don't think that will solve anything.

Here's a quick screen capture of me trying to launch:

for additional reference

$ java -version
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

Nope it didn't.

$ ls ~/.minecraft/bin
md5s  version

cd ~/.minecraft
mv bin bin-old

<launch minecraft via the launcher jar again>

Same error 😞 ---- Oh wait, I forgot to say force update. (but I don't think that'll fix it)
