If you’re seeing Error Code 0x643 on your Windows 10 computer, it means that there’s a problem with your Microsoft .NET Framework installation. This can be caused by a number of things, but the most common cause is a corrupt or damaged installation file.

What is Error Code 0x643?

How to fix Error Code 0x643

If you’re seeing error code 0x643 when trying to install updates on your Windows 10 machine, don’t worry – you can easily fix this problem.

First, try restarting your computer and then checking for updates again. If that doesn’t work, try running the Windows Update Troubleshooter. You can download this tool from Microsoft’s website.

If the Windows Update Troubleshooter doesn’t fix the problem, you can try resetting the Windows Update components. To do this, you’ll need to run a command in the Command Prompt.

First, open the Command Prompt as an administrator. To do this, search for “Command Prompt” in the Start menu, right-click on the Command Prompt shortcut, and select “Run as administrator.”

Once the Command Prompt is open, copy and paste the following command into it, and hit Enter:

Net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

This will stop the Windows Update service, rename the SoftwareDistribution and Catroot2 folders (which store update files), and then restart the Windows Update service.

After running this command, try checking for updates again. If you’re still seeing error code 0x643, you can try manually installing the updates that are failing to install. To do this, you’ll need to download the updates from Microsoft’s website, and then install them manually.

If you’re still having trouble, you can contact Microsoft support for help.
