NCover error

I ran into a problem when adding NCover to our UnitTests on a new project the error I got when using NCover with Gallio was the following, Profiled process terminated. Profiler connection not established. The FAQ that is in the NCover directory bundled with Gallio suggested - If using the command-line, did you COM register CoverLib.dll ?

Sure enough, just run
>regsvr32 CoverLib.dll
from a command prompt, that fixed the problem on both our build machines.
