Next time you release a patch for Office Communications Server, hows about making the patch gracefully fail if it’s prerequisites aren’t met.

Like, say, a system component needing to be installed that wasn’t required previously.

If anyone else tries to install KB967831 for Office Communications Server 2007 R2, bear in mind you need to install MSMQ on the server first.

That’s 1 hour of my life I’m never getting back.
