You have multiple versions of Java installed. Please remove update 21 and any other Java version besides 7 update 45. Then if you are still having problems post a new console log.

You no longer have any other version of Java installed besides the 64bit version of 7 update 45? No 32bit versions? If you do uninstall them. If that does not work or you have only 64bit 7 update 45, try changing your language to English temporarily. I know of some users who changing language to English fixed a few errors.

The log still says you have multiple versions of java installed.

Remove the other versions then post another console log once the other versions have been removed.

You have the Java Development Kit installed and you should be using the JRE one. Remove all versions and install the latest x64 one from here then try again.

Normal minecraft works just fine I don't know what's the difference and I need the jdk.

Try it with the JRE to see if it works. The new update to the launcher checks java versions and can cause problems with more than one installed.

I assume you are creating apps and such with java.

I am just trying reinstalling the jdk, if that doesn't work i will check your idea and yes java is one of my favourite languages.

Please give the basic troubleshooting guide a try for me here incase the launcher is screwed up. Please make sure to follow all the steps.

I would also suggest allocating between 2 and 5Gb to the launcher because anymore and you may have issues.

nothing works

Did you try the guide out? If so let me see another log incase the error has changed.
