SOLVED-UDKLift.exe wont start Editor. Any build, Win7 64bit

Hi folks,

Now I spend some time on google and did a forum search so here it goes:

I bought myself a new laptop since my old one broke. I thought I spend extra money to get something that can run UDK.
Specs are:
Windows 7 Home Premium 64
Dx11
4Gig ram
Intel i5 2.3 Ghz
Nvidia GeForce GT540M

And it was just bought yesterday-

I first downloaded the Oktober release and Installed it along with the MS Framework 4. I can start SpeedTree, FrontEnd and the Launcher.
I can´t start the Editor itself. Everytime I klick on UDKLift or use the menue shortcut it loads something for half of a second and then nothing.

I tried to run and install it in different compatibility modes wich didn´t do anything.

I tried to start the UnSetup.exe and it says it can´t start because the UDK package is damaged. Win7 advised me to reinstall everything, wich I did with no effect.

I downloaded older versions= Same effect. Everything works but the editor itself and UnSetup

Any Idea what is causing the trouble? I´d really appreciate it. :(

Fixed it myself.

Was suprisingly easy after a good night of sleep. I just opened the preferences of the UDK.exe game launcher and added an "editor" at the end of the file path. Still I wonder why it doesn´t work via UDKLift.
