Office for Mac 2008 just asked me whether I wanted to update. However, on continuing with the update, a Window popped up saying that I needed to close Chrome before the update could continue. I find this rather suspicious, since Office should not need to go anywhere near Chrome.

Any idea why there might be a legitimate reason for this, or alternatively, just what is Microsoft trying to sneak on to my computer?

I did look at the download details on Microsoft's website, but aside from the general guff about closing all open applications, it doesn't mention anything about Chrome or any browser plugins.

Because Office 2008 also updates Silverlight, this is totally safe, yet very uncomfortable; as usual, when it comes to Microsoft :-)

Ah, that would explain it! I was racking my brains trying to think of any Microsoft software that I had, apart from Office... –  Chinmay Kanchi Feb 4 '11 at 0:30
I don't have Silverlight installed, yet it still wants to close Chrome. –  drfrogsplat May 13 '13 at 5:02

I just installed a Silverlight update with Chrome open on my Mac. The installer did not complain, and completed seamlessly. However, I have a Office 2011 update that still refuses to install until I close Chrome.

This is pretty strong evidence that Silverlight is not the culprit. According to this blog post, it's because the update fiddles with fonts. Still a terrible UX, though.
