Microsoft’s recent security update for Office, caused some big issues for quite a few users of Office 2013. According to the Microsoft engineering team, about 1% of users were unable to launch their Office products after this update was installed. This issue affected people using the Office 365 subscription and the stand alone Office 2013 .While the percentage is small, that’s still a whole lot of people, considering that there are millions of users of Office 365 and Office 2013 – it’s enough people to populate a small city. Users report seeing this error when they try to launch: We couldn’t start your program. Please try starting it again. if it wont start, try repairing Office from “program and features” in the control panel.
The problem seems to be isolated to click-to run users. Click-to-run allows users to access Office programs without fully downloading the whole program to their computer. Using click-to-run, you could have multiple versions of Office installed on the same computer. Click-to-run products also update automatically and you can continue to use Office while it updates in the background. Office runs in a self-contained virtual environment and doesn’t change other products installed on the computer.
It can be handy for things like testing out a new version of Office to see if it works with your system.
Products possibly affected by this bug include:
Office 365 ProPlus
Visio Pro for Office 365
Project Pro for Office 365
SharePoint Designer 2013
Lync 2013 Basic
Office Professional 2013
Office Home and Business 2013
Office Home and Student 2013
