I recently started rolling out some computers that came preloaded with Windows 10 Professional and Office 2016 Home & Business OEM. We rolled them out earlier this month and about a week ago all 4 of them lost the ability to use their Microsoft Office Applications. I don’t know if it was an Microsoft Office update or some other issue. I tried the Quick Repair and Online Repair and both failed. I tried uninstalling Microsoft Office and running all the clean-up utilities and still I was unable to reinstall Microsoft Office 2016. I was able to get a copy of Microsoft Office 2013 to install, but that doesn’t solve the issue. I worked with Dell and Microsoft for at least 8 hours each and none of them were able to resolve the issue either. Both companies ended the conversation with recommending a fresh Windows 10 install. That wasn’t going to work for us.
So we bought a few licenses of Office 365 Premium but even that would not install. We discovered that if we uninstalled our Kaspersky Endpoint Security that we could get Office 365 to install. Then we could reinstall Kaspersky. We were never able to get Microsoft Office 2016 Home & Business OEM to install. So hopefully Dell can refund us for those licenses. My coworker is contacting Kaspersky support to try to figure out what could be causing the Endpoint Security to not allow Office to install. I just wanted to share this in case someone else comes across this same “Perfect Storm” of software products and its associated woes
