When ever I open minecraft nothing happens so I click it a lot of times really fast till there are like 25 minecrafts at the bottom of my desktop- then they stay open- but they soon say FATAL ERROR something to do with the bootstrap- says-

FATAL ERROR: net.minecraft.bootstrap.FatalBootstrapError: Unable to un-pack java.io.IOException: identical inner class

at net.minecraft.bootstrap.Bootstrap.unpack(Bootstrap.java:159)
at net.minecraft.bootstrap.Bootstrap.execute(Bootstrap.java:123)
at net.minecraft.bootstrap.Bootstrap.main(Bootstrap.java:381)

Please fix the error and restart.

What version of minecraft / java are you using?

I am using Java 7 update 60 and I cant choose a version of minecraft to play on because the launcher wont start but if I could I would be playing on 1.7.2Java 7 update 60 and the launcher of Minecraft wont start so I cant choose a version to play on but if I could it would be 1.7.2

Java update 60 minecraft 1.7.2 if it would start

Its still not working I removed all Java programs restarted and downloaded the latest and it still doesn't work!

Just a note for anyone who has this problem. Do NOT hit the free download button. That's the 32-bit version. Always make sure to find and download the 64-bit. Had computer cleaned and had java updated, unfortunately installing the 32-bit.
