Re: [Win7SP1 x64] Unable to install Windows Updates. WU error code 0x80070643.
OK, here's what we need to do.
If you don't use Dragon Naturally Speaking, please uninstall it as it's causing crashes/conflicts. Likely not related to this update issue but wanted to let you know.
Please uninstall Norton Security Suite/N360 temporarily while we troubleshoot. Security Suites often are the cause of such issues and I want to make our lives easier by removing it just while we troubleshoot.
Once this is done, attempt to install the .NET update. If it fails, please do the following.
Step#1 - Capture Process Monitor Trace
1. Download and run
Process Monitor. Leave this running while you perform the next steps.
2. Attempt to install just the one .NET update like you have in the past.
3.
Stop Process Monitor
as soon as the update fails. You can simply do this by clicking the
magnifying glass on the toolbar as shown below.
4. Select the
File menu...
Save... and save the file to your
desktop. This is likely the default location. The name (unless changed) will be
LogFile.PML. This is fine.
5. Zip up and attach the
LogFile.PML file as well as your
CBS.log.
