In an update for MS Office for Mac, the installer asks to close Chrome and Safari — why?
What do those programs have to do with Microsoft Office?
I only have Word, Excel, and PowerPoint.

Presumably, the Office installer can modify/update the Microsoft
Silverlight.plugin (which is installed in
/Library/Internet Plug-Ins/), which Safari and Chrome could potentially be using.
It's primarily just a precaution against updating files which an application is actively using.
After further investigation, it looks like it's actually the fact that the installer modifies the fonts in
/Library/Fonts/Microsoft/ which is the motivation behind requiring that several apps not be running. The following is an excerpt from the XML
Distribution script that's in the
16807Office 2011 14.3.5 Update.pkg installer package:
<choice id="fonts" selected="true" start_enabled="false" start_selected="false" start_visible="false" title="fonts-title"> <pkg-ref id="fonts"> <must-close> <app id="com.apple.Safari"/> <app id="org.mozilla.firefox"/> <app id="com.google.Chrome"/> <app id="com.operasoftware.Opera"/> <app id="com.microsoft.Word"/> <app id="com.microsoft.Excel"/> <app id="com.microsoft.Query"/> <app id="com.microsoft.Powerpoint"/> <app id="com.microsoft.Outlook"/> </must-close> </pkg-ref> </choice>
Another pair of potential culprits are
SharePointBrowserPlugin.plugin and SharePointWebKitPlugin.webplugin
They are installed by default with Office 2011 under
/Library/Internet Plug-Ins. (Note: Silverlight was not an option to install with 2011).
None of the above!!! just force quit Google and that's it!!
