According to the MS CVE site (https://msrc.microsoft.com/update-guide/vulnerability/CVE-2021-34527), I am trying to download the patch for Windows Server 2008 R2 SP1 (https://www.catalog.update.microsoft.com/Search.aspx?q=KB5004951) but when I try to install that, I get the error: "The windows modules installer must be updated before you can install this package. Please update the Windows Modules Installer on your computer, then retry Setup." The link takes me to (https://support.microsoft.com/en-us/topic/error-message-when-you-install-a-msu-update-package-on-a-computer-that-is-running-windows-the-windows-modules-installer-must-be-updated-before-you-can-install-this-package-fe8d5770-df2e-f020-b47c-6605b0de15ba) with a link to download (http://www.microsoft.com/download/en/details.aspx?familyid=1de747cb-dee1-4826-a8ff-6491d2445f00) but I get a 404 error when trying that link.
Please help - I need to download the Windows Module Installer in order to download the patch for Print Nightmare to protect my server.
