When is the VSTO-Runtime needed when using a VSTO-AddIn?

I have a VSTO-Add-In for Outlook and need the information when i have to provide the VSTO-Runtime with the installation of the Add-In.

I have already found this article describing the prerequisites but I could construct cases which do not fit this description:

The article says "If Office 2010 Service Pack 1 (version 14, build 6029) or any newer Office version is installed, Office will take care of configuring the VSTO runtime." => This is telling me I do not need to provide the VSTO-Runtime in this case.

In the case that I have installed Office 2010 and manually install the ServicePack 2 I have the buildversion 7015 in my Outlook which is a greater version than 6029. Version shown in Outlook

My installer recognizes this and does not provide the VSTO-Runtime.

But on starting Outlook after the installation I get an error saying, the .vsto-file could not be read. enter image description here

This error only disappears after installing the VSTO-Runtime. Then the AddIn works fine.

What are the real cases in which i need to provide the VSTO-Runtime?

Interesting question... I was not aware of the fact that with some version of Office the VSTO runtime installation could be omitted, I have always bundled the VSTO runtime in my wix bundle installers. - Benoit Patra

if you're using windows installer, just add it as prerequisite, which will create a Setup.exe, and add it as Launch Condition in your installer to show an error message, that Setup.exe should be run, or just make the Setup.exe run always, it will launch your .msi

have a look here - I guess this is also valid for Office 2013 .. just use the right components IDs !
