Hi,

Thanks you for posting your reply and update.

I suggest you to disable Antivirus and security-related products, if you have any Antivirus installed for (Free) uninstall it, if not then disable the Antivirus, try again to update and check if issue is resolved.

Disclaimer: Antivirus software helps protecting your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software and\or troubleshoot any pertinent issue, you should re-enable it as soon as you're done. If you are connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to malware attacks
