Use this to ‘roll back’ to a previous known-stable build. Updatetoversion lets you choose a specific past version of Office to install. There’s another option available in OfficeC2RClient.exe that’s really handy if you’re having trouble with the latest update. Switch to specific version – updatetoversion Not recommended because usually startup tasks are crowded enough already without adding more!


That’s it! You should now be back in business and be able to download and install the updates. Launch any of the Office apps, then click Help > Check for Updates, then click Install. Now enter the following addresses: 8.8.8.8 and 8.8.4.4, then click OK. Next, click the DNS tab and then the Add (+) button at the bottom. Launch System Preferences and go to Network > Advanced. The not-so-obvious solution I have found for this is to use Google’s public DNS address. Either it’s a compatibility issue with OS XYosemite’s version, or Microsoft is not aware of the problem yet. It turns out the culprit was the DNS server Microsoft uses to connect to the public Internet. I even tried to download the update manually, but Microsoft’s Support page behaved unresponsive, even in alternative web browsers.

Unfortunately, checking for Updates from the Help menu was not working.

To download the latest updates for Office 2016, I needed to have AutoUpdate version 3.4 installed. Resolve Office AutoUpdate for Mac, not Working
