The nacmnlib71.dll file is a naCmnLib module that is a part of the McAfee Common Framework from McAfee, Inc. The Common Framework is a component of McAfee’s antivirus software, and this file is a piece of the network scanning functions. If you are seeing errors with this file, the live scanning ability of McAfee may be compromised. A reinstallation of McAfee may fix the issue, but the problem is more likely in your Windows registry.
The registry works as an information booth for Windows, keeping track of where all your installed files are located. Every time software runs on your computer, Windows checks the registry to find all the files it needs. If there is a mistake in an entry of the registry, Windows won’t be able to find and use files, and your software will break.
