Yeah I thought maybe an email qould be quicker - The install has to extract the world just to do that simple installation piece. I would think they should tweak the process to let you pick FIRST, so it knows what to extract - but that's just me and not connected to helping him.
So, yes, by all means perform an install of JUST channel tools. Make sure you uncheck the Program Files box at the top of that whole list of check boxes.
Let's get THAT fixed, and then deal with the slowdown on close issue.
