Hi! I've managed to get our computer into quite the mess, and I don't know how to fix it, and I really hope someone out there can help me!
We upgraded to IE 11 but didn't like the new version of outlook that came with it, so I uninstalled the update to bring it back to IE 10. I then uninstalled that update to hopefully get us back to IE 9, but it reverted all the way back to IE 8. We now seem to be stuck with IE 8, and when I try to install either IE 10 or IE 11, it goes through the entire installation process, but at the very end, gives an error message that Windows cannot finish the installation. I went through all the troubleshooting steps I could fine - did a clean boot, tried to install it in safe mode, turned off the firewall, checked to make sure we have all of the pre-requisite updates and ISP-1 (which we have). Also, now, we can't open Outlook on IE 8, when we had been able to do so before. We can enter our username and password, but then it says "Page not found." I'm just at a loss. Microsoft customer support was no help, since I had already done the things they suggested. We're running Windows 7. Would it help to upgrade to Windows 10? Should I try to install IE 9 and then try 10 or 11 from there? Please, I hope someone can help!
