Random popups from Outlook 2007 trying to installing from "a network resource that is unavailable"

Question

Ever since I received the Windows 10 Anniversary update a few days ago, I get a frequent popup stating "Please wait while Windows configures Microsoft Office Outlook MUI (English) 2007". Immediately after it starts "configuring", I get a popup asking me to locate an install file.

I want to stop it from popping up!

The feature you are trying to use is on a network resource that is unavailable.

Click OK to try again, or enter an alternate path to a folder containing the installation package 'OutlookMUI.msi' in the box below.

Use Source: [G:\MSOCache\All Users{90120000-001A-0409-0000-0000000FF1CE}-G]

But I don't use Outlook. I don't want to install this. If I cancel it, it comes back in about an hour. Over and over.

The process runs as dllhost.exe, so that's not very helpful.

I opened it in Process Explorer to try to find exactly what is going on, but I don't really know what I'm looking at. Here's some info from process explorer:

Path: C:\Windows\SysWOW64\dllhost.exe
Command Line: C:\WINDOWS\SysWoW64\DllHost.exe /Processid:{3BFADDE5-09ED-42AE-8190-2E68B650CFE6}
Parent: svchost.exe(764)

Any ideas to try to kill this thing? Thanks!

I found Microsoft Office 2007 Enterprise trial was installed on this computer. I never knew about it and certainly never used it. I guess the anniversary update triggered the Outlook install randomly. Weird.

Uninstalled the trial and it hasn't come back. In hindsight, I should have checked programs & features sooner.
