Windows 7: Device Driver Software was not Successfully Installed for Cable Modem

21 Jul 2012   #1

Windows 7 Professional x64
Device Driver Software was not Successfully Installed for Cable Modem

Hello everyone,

When trying to install my USB cable modem (Scientific Atlanta DPC2100R2), I'm always getting a popup message that says "Device Driver Software was not Successfully Installed." I don't even get a "Found New Hardware" message beforehand. I just switched over to Windows 7 Professional 64-bit from Windows XP today, and the modem was working fine earlier (when I was using XP).

When I put the Setup disk that came with my modem, AutoPlay will play it, but I can't set up anything that way. If I go through Device Manager to try and update the driver, I get a message along the lines of "Windows could not find updates." I even get this message when I manually direct it to my D: drive where the disk is.

I've even tried uninstalling the driver from Device Manager, unplugging the USB from my PC, restarting it, and then plugging the USB back in, but I still get the same error.

It really shouldn't be the modem, as it was working fine earlier and I am even using it right now as I type this on my other PC (that runs Windows XP) and it's working fine. Would anyone happen to know how to remedy this? I've run out of ideas, so any help would be greatly appreciated.

Windows 7 Ultimate 64-bit
Device Driver not Compatible?


Upon checking on the Manufacturer website for your cable modem, I suspected that the driver for your device is not compatible with Windows 7. I also went to the Windows 7 Compatibility Center, and could not find your device listed on the site.

Here is the site, for your own research.

Windows 7 Compatibility: Software Programs & Hardware Devices: Find Updates, Drivers, & Downloads

My solution is to find if there is a generic driver for your modem, on the Cisco website, simply download the driver that best suits your modem's series.

Windows 7 64-bit

I tried the company's website. The "Complete Scientific Atlanta Cable Modem Installation CD" available for download doesn't have Windows 7 drivers on it (at least not for my 64-bit PC). I tried using it. There aren't any other Windows 7 listings. Help!

Windows 7 Ultimate 64-bit

Hi all,

So as I suspected, the issue most likely stems from incompatibility with Windows 7. I'll try to research alternatives with your current hardware. But, usually if the driver is meant for a 32-bit OS it will not work for a 64-bit one and vice versa. You may have to look into investing into another modem, or a wireless router that will be helpful with your new OS.
