Samples don't run

Has anyone had a similar problem?
I installed the toolkit, and driver… (on windows 7)
Then i tried to run the device query, it starts the command prompt but doesn’t finish the sample.
Any suggestion?

Hi Lisbeth, can you post the output of one such sample? If deviceQuery fails, this will be the best one to start with. Thanks!

Hi Tamarzan,

Actually there’s no output at all.
It only starts the prompt… And I have installed the toolkit and the driver…
Do you know what that is?
