blender wont start

i installed blender with internet explorer open thinking it wouldn’t matter when it says it is recommended shutting down all programs first.

well i uninstalled it and re-installed it without any programs open, but blender still wont run.

i double click on the shortcut and i get an empty command prompt window and then it disappears, nothing happens after that.
i opened the task manager and i could see the blender process start for about 2 seconds and then disappear.

i’m on windows 7 home premium 64bit
blender version 2.69 64bit

is there anything i can do besides reinstalling windows to get blender to run?

i figured it out…

i can’t use virtual audio cable and blender at the same time.
crashes the installer version and the .zip version if i’ve got my default soundcard set to the virtual audio cable.
