The MSI deployed fine.
For the config, I sent the welcome message after modifying part of the text to tell users to run the attachment to config the app.
I do not see how I could "map" a user/computer and extension to autoprovision, so I don't think that would be possible or helpful. The only thing I could think of would be to take the config files and put them in a Startup folder.. but that seems more messy.
