Cannot Get My Computer To Use Drivers For My Printer

I have a Windows 7 64 bit computer, almost brand new. I also have a Dell AIO 926 photo printer that i wish to connect to it. When i connect it, the computer recognizes it as normal, but says i need to download the drivers. I click troubleshoot, follow its instructions, download the correct driver(made sure when i looked manually on the dell website), for 64 bit windows 7. Only thing is, i still cant get the printer to work! it still says "troubleshoot" and wont let me print anything. and every time i "troubleshoot" it says i need drivers for it, which it did before, and just takes me in a continuous loop, getting nowhere. I then downloaded it from dell website manually( i made sure it was for 64 bit, not 32) and still no luck. i can stare at the drivers all day but i cant get my computer to use them on my printer. it just detects theyre not there. the drivers are installed to the main hard drive C:, under dell/drivers/R150575. is it installed in the wrong place? i couldnt find a different place to install it in the drop downs, and it seemed like a good place to install it. i have also restarted the computer to make sure, and disconnected & reconnected the USB; still no luck for both, still that dreaded exclamation mark next to the printer under "hardware and devices".
