Laptop WIn7 won't load FTDI drivers

Hello all. I'm trying to install the FTDI drivers on my WIn7 laptop so I can upload sketches to my arduino nano. I was able to install the FTDI drivers on my Win7 desktop computer and it works fine now. I just can't get the drivers loaded on my laptop. I've watched several videos on youtube and followed all the instructions. Need some ideas on what to do.
