So, I bought minecraft and whatnot, but when I try to run the launcher I get this:
Starting launcher. FATAL ERROR: net.minecraft.bootstrap.Fatal Bootstrap Error: Unable to start: java.lang.reflect.InvocationTargetException at net.minecraft.bootstrap.Bootstrap.startLauncher(Bootstrap.java:242) at net.minecraft.bootstrap.Bootstrap.execute(Bootstrap.java:124) at net.minecraft.bootstrap.Bootstrap.main(Bootstrap.java:381)
Please fix the error and restart.
I went to my laptop and it went perfectly fine, but the laptop is a potato and can hardly run it above 20fps, and it doesn't have an lcd on it.. My desktop is the one I want to use it on because it's my main computer. please help
The problem: InvocationTargetException wraps another exception that occurs through reflection.
This means that the InvocationTargetException is pretty much useless without knowing what exception caused it.
Unfortunately, the way the launcher currently handles and reports errors, it will not show the original exception that occurred.
This makes figuring out what is causing this exception very difficult.
My solution:
I wrote a tool that will do two things: 1. Download the latest version of the launcher from minecraft.net 2. Patch one file in the launcher so it reports the full exception.
You can download it from here (jar file download).
I recommend everyone having this problem to download my tool and run it.
Then copy and paste the error log to your respective threads. (don't hijack this one)
Hopefully we'll be able to determine the cause of this error, and resolve it.

Turns out that It was my taskbar theme.. wow, didn't expect that to be it. I figured from the errors it stated.
I fixed it by putting the downloading that LZMA file and putting it in a folder with mc not the jar the starter like the grass block and mine works but it still shoes the white screen but it starts the launcher so
ok i know im late but im getting the same error and i want it fixed, how do i figure out if i have a different theme, and how do i fix/change it so i can play minecraft again PLEASE HELP

I've done all that numerous times. If anything, my laptop's java is more out of date.
What version are you using?
1.7.0.250
It seems somewhat common, but unresolved..
Contact me on skype @ adamskyler1990 (my name is Eli, at the time, I liked to get free op on small servers, so that was my scheme )
Is your copy of windows legal?

It's looking like this exception is thrown most of the time by a problem with Java's LookAndFeel.
Do you have a custom Windows theme by any chance?

Yeah I did. I fixed it and minecraft works now I can just revert, then go back when minecraft launches.
I posted a solution here, so you don't have to revert your theme to launch Minecraft.

Alternatively use JDK8.
