I have a third party VSTO file and need to get this to install silently without interaction from the user. Not sure how to add this to my project. Any tips?
I would recommend creating a separate installer for your VSTO file using our predefined support for Office Add-ins. Then this installer could be added as a prerequisite to your main setup (with silent install command line).
These are the steps for achieving this:
1. Create a new "Office Add-In" project from "Add-Ins" project type. Our Office Product Add-in will be displayed. After completing the wizzard, build the project.
2. Go to "Prerequisites" page of your main project. Add a new feature based prerequisite. Select the MSI from the Office Add-in project. If you need to install this Add-In silent, you could go to "Setup files" page of the prerequisite and enter "/qn" command in all "Install Command Lines" fields (Full UI, Basic UI, Silent).
