Windows .exe Minecraft won't launch

[xSquaRx]

When I try launch via FTB launcher minecraft doesn't launch, mods enabled or mods disabled. It says minecraftlauncher said -1. Also happens when I use the .jar version of the launcher and anti-virus disabled.

OS: Win 7 64-bit
Anti-virus: Kaspersky Internet Security 2013
FTB Launcher Version: 1.0.5
Minecraft Version: 1.4.2
Java Version: 7
Pastebin log: http://pastebin.com/5ZKjMU5t

First try lowering your max memory setting back to the default 1024 and see if that helps. (it shouldn't really, you seem to be running java 64bit, but still worth a try to rule it out.
If it don't work, try running the launcher with adminsrator privelages and see if that helps.
If that don't work try temporarily disabling kaspersky and see if that helps.
If your error log changes during any of these steps please post it here.

Are you running the launcher as an administrator? If not, try doing so.

I solved the issue. Java was set to run as admin but windows blocked the pop up for me to allow it to run. Set Java to not run as admin and all is good. Thanks

I'll keep this bit of knowledge! It will certainly come in handy for others with a similar problem! Do you mind if I link this thread in my CP&S?

It would look something like this:
