VSTO Runtime Installation

I noticed the below in the MSDN documentation concerning the VSTO runtime installation.

"How to: Install the Visual Studio Tools for Office Runtime - You do not need to install Microsoft Office applications on computers that you install the Visual Studio Tools for Office runtime on. For example, you can install the runtime on a server and use the ServerDocument object to access document files. If you do need Office applications on the computer,
install them before you install the runtime. If you install Office after installing the runtime, you must run VSTOR.exe again and repair the installation."

This seems like a hassle, since the end-user will install my app and I have no control over whether they install it before and/or after MS Office. I just need it to "work" :-)

Has anyone figured out a smooth way to package the VSTO runtime with your app such that it "just works" Is there some way of detecting that VSTO needs to be re-run
