InstallUtil
Installutil seems to have stuffed up on my computer. It gives the following error whenever I try to start it, even without parameters:

The Application log contains the following dump: Faulting application installutil.exe, version 1.1.4322.573, faulting module codecoverage.dll, version 1.0.0.1, fault address 0x0000639b. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. SOLUTION The problem was caused by the Code Coverage tool I was using (Coverage Eye.Net) (see
http://www.gotdotnet.com/Community/UserSamples/Details.aspx?SampleGuid=881a36c6-6f45-4485-a94e-060130687151).
I renamed the code coverage directory and viola, all was well again.
