Retail Plus Mini Wireless USB Adapter  

I recently purchased a Compaq Presario desktop with no integrated wifi. So I picked up a usb adapter. The Retail Plus website says the adapter is compatible with Windows 7. However, after I run the setup and plug in the adapter, the drivers do not install. My apartment is wireless only, so I can't connect my desktop to the internet to download drivers. I do have a laptop with wifi, so I tried installing the usb adapter on it. Everything went smoothly and the usb works on the laptop. So I tried putting the drivers on a disc and putting them on the desktop, no luck. I downloaded a package from the Retail Plus website and I still cannot get the drivers to work.

Unfortunately, I am not very computer savvy. Any suggestions to make this work?

Thanks for replying so quickly. Unfortunately the problem is not with the laptop, but with the desktop. I restarted and I am still getting the message that says the device driver software was not successfully installed. I can't connect the desktop to the internet for it to look for solutions itself.
