Hello Minecraft forums, I've download Minecraft 1.7.5 launcher and reached this error during the installation phase and wonder what I should do to get Minecraft to launch & install.

Please fix the error and restart.

Having exclamation marks or other special characters in your Windows username can break Java, which in turn breaks Minecraft. To fix this issue, either create a new Windows account without any special characters (only A-Z and 0-9), or change the working directory of the launcher.
See http://hopper.minecraft.net/help/special-characters/ for more information on working around this problem.
