After waiting about 3 hours, I said the heck with it and uninstalled MWO and then went to the website to download a newer copy, hoping that this would speed things up. when I went to install it failed out and said I still had a copy installed. I searched my hard drive and insured that all files were indeed deleted, restarted and tried again with the same result.
So I filed a support ticket, about 5 days later (I see support response times have not improved) I received a response directing me to use Microsoft's uninstall fixit tool. Which I did to no avail. I have reopened the support ticket and thought that while I as waiting another 5 or so days for a response I would see if the current player base had any suggestions.
