That error can appear whenever the MSI code has been corrupted, no matter whether .NET 4 or not. or, because the MSI installer is earlier than version 3.1.

The new MSI installer is here:

www.microsoft.com/en-us/download/details.aspx?id=8483



error 643 is identified here:

There are some sites that offer an MSI installer fix, but if your version is older than 3.1, you need to upgrade anyway. Run a search on MSI installer.

.NET version 4 is generally used for network administration, or possibly by some device connection such as Nokia Suite. It also slows down a computer.
