We have become aware of a critically-broken Office Update that Microsoft began pushing to users this past Tuesday, November 12th.
The update, once installed, will immediately break a number of key Microsoft Office features and many Office add-ins, including OnePager. It also will break any third-party applications that rely on certain Office components to be functional on your system.
In short, it is an unmitigated disaster.
To learn how this impacts your use of OnePager, read here to get more details, and to learn how to fix the issue so that your access to OnePager is not interrupted.
For more general information on the issue, since it impacts many other applications beyond OnePager, read here, and here.
In the meantime, if you have not already been hit by this update, please temporarily suspend Office Updates until Microsoft has released a fix. To turn these off, launch Excel, and go to File > Account > Update Options. Choose to Disable Updates
If Microsoft provides us with more information on how to stop this issue from happening without waiting for their next update to be pushed, we will let you know ASAP.
