Maybe a good idea to ask Mcafee for a cd to save the 9 hrs download
If Windows 7 was up to date you should have had those MSXML versions and many updates since already installed.
When this is all fixed and if you haven't got it already, install Service Pack 1 for Windows 7, help with that here: https://community.mcafee.com/docs/DOC-2205 and make sure updates are turned on as there have been plenty since that.
Hint: never use registry cleaners as this sort of thing can happen when using those.
