0x643:The resolution of the error code of Windows update

Error Code:0x643
Explain how to deal with this error code. If you try to upgrade .NET, you may get a 0x643 error.
At that time, it seems that the error code "1603" of the installer may be displayed at the same time.
This seems to be mainly a problem with the MSI (Microsoft Windows Installer) installer. In short, it's not an Update issue, but an MSI issue that installs Update.

If the .Net update fails, the .Net needs to be repaired.
