I've always just chosen the install without the MDS Integration Service because no one has ever asked about app development here before, but yesterday I had a developer ask if he could try out a test .net application

Is my only option an uninstall of 4.1.6 and a reinstall to get those components on my BES servers?

Thanks.

Yup as far as I know. If you try to modify the install it will just uninstall it anways.

Wow that really sucks if your right. You would think a component like that would be able to be installed after the fact. None of our devs have a BB so hopefully I never need to install MDS.
