Try switching off the antivirus in your PC. It has been found that it blocks some important updates for the PC also. After that, remove the previously downloaded files and do a new download from this link. This would definitely solve the problem.

You may receive error code “643” or “0x643” when installing an update for Microsoft .NET Framework versions 1.0, 1.1, 2.0, 3.0, or 3.5. If you are trying to update or install an update for Microsoft .NET Framework 1.1, just download Microsoft .NET Framework 3.5 Service Pack 1. This might fix the problem if you are running the web installer for Microsoft .NET Framework.

The link above downloads the offline installer for Microsoft .NET Framework 3.5 Service Pack 1. Once the file is downloaded, you can run the installation without internet connection. If this doesn’t work, right-click the network icon on the system tray and select “Troubleshoot problems.” Follow the steps in the wizard to diagnose and fix any network related problems.

Microsoft .NET Framework 3.5 Service Pack 1 includes all related updates for Microsoft .NET Framework 1.1 as well as .NET Framework 2.0 Service Pack 2 and .NET Framework 3.0 Service Pack 2.
