Launcher wont even start??? [NOW FIXED][PLEASE READ]

[LuciusDerEwige]

So I had the same issue with trhe same error output as Mattimus. I resolved it by performing all of the steps in this guide. I found I had a few versions of Java installed. Once I deleted them all and only installed the latest Java 7 build, the launcher opened properly. If this helps please spread the word. I've been seeing a lot of posts about this error.lately.

Thank you zzZombie, it works. I uninstalled all but the newest Java 6 and Java 7 Updates and now it works.

You have to uninstall all versions of Java, and only have Java 7.

No I left Java 6 Update 30 on my machine and only uninstalled older updates of Java 6 and it worked. At least now the launcher starts and the DW20 pack is downloading.

But...why?
Edit: you don't need both there.

 

[LuciusDerEwige]

I'm currently writing my Bachelor exams with Java and I don't want to change to much around. It worked, so I stopped uninstalling.

I cant backup the worlds now.. do i have to make a copy of the 'Saves' folder or can i go into 'Backups' and copy the Direwolf20 one? theres no Saves folder on my ftblauncher anymore..

 

[Ashzification]

You have to make a copy of the "Saves" folder. Backups only has (or should have) configs

You have to uninstall all versions of Java, and only have Java 7.

I did exactly this, but I still get the same error for starting the launcher as well.

Also, I just discovered that even closing the console, there still is javaw.exe running in the processes background in the task manager.

I've also submitted the ticket here:
