Windows 7 Problem with my Dell aio 926 printer

[gaudino]

I installed windows 7- 64 Bit on my notebook. It's working great, but I have one big problem. My Dell aio 926 printer(is one of the all in one printer) isn't working. I tried almost everything but without sucess. At first I downloaded the driver from dell and installed it, but after the window which says installtion sucessfull. After I closed this window another one popped up and says: The driver for your dell aio 926 isn't installed, please uninstall the driver. I did it and reinstalled the driver, but the same problem. After I uninstalled the driver again, I dowloaded a programm from dell which cleans your pc from all dell drivers. I used it and installed the driver again, but the same probelm. I also treid to find a solution in web but without sucess. My notebook is a fujitsu siemens amilo 1,6 ghz with 2048 mb ram. Thank you for help!!!
