Put the summary of the bug you're having here
What I expected to happen was...:
The game would open and I would go on my merry way building and killing things
What actually happened was...:
The game crashed...after I went back and found a version that the launcher would actually successfully get launched. 1.7.10 in this case, anything more recent I get a fatal error before it can even open.
Steps to Reproduce:
Get on my computer, open the minecraft launcher 1.6.11 java version or non-java, click play, watch in despair as the game does not open.

this is the error coding in the launcher.

Marking this as resolved and sending me to a topic that I have already read and doesn't apply to my situation is in no way helpful. I don't run Norton, or McAfee or any other brand of antivirus that is known to cause those issues. I run Kaspersky and have already made sure its not blocking or overriding anything from Minecraft, Java, or Mojang in general. I've already uninstalled and re-installed, deleted the files recommended, reloaded the files recommended and even went as far back as 1.6.2 version to try and get it to work. Clearly this is a code issue that didn't occur until AFTER the update to 1.8.3
Incomplete without a crash report. Please attach it so the issue can be diagnosed.
