Win 10 update failed to install error 0x80070643

Hi,

The error code 0x80070643 is commonly caused by .Net Framework installed on the computer. We suggest addressing the 0x80070002 error code first because this issue occurs when some files in the Windows Update are missing. We can solve this error code by following
the troubleshooting steps suggested on this article.

Note: The troubleshooting steps for Windows 8.1 also applies to Windows 10.

Update us with the outcome so we can provide further assistance.

 

Clean Install after upgrade, 32b Windows 10 pro to 64b Windows 10 Pro

I've upgraded 4 x PCs to Windows 10 Pro - OK. 2 were 32b, 2 were 64b.

Can I now do a 64b clean install to the 32b Windows Pro upgraded PCs, reformat etc. under the terms of the upgrade?

I have made the 64b DVD ready ;-)

Thanks.

John
