The problem with this is the copy command is running in the only thread - there is nowhere to stand off to the side and track the progress. If the EXE is large, I suppose before you run the copy command you could launch another program that would look at how close to the size of the exe being copied the local copy was, with a timer and checking the filesize. To me this seems rather awkward. If you were writing a low level routine to copy the exe byte by byte you could look at progress, but again I think this is rather cumbersome unless it is one monster exe. I would test to see how long it takes to download on average, and give a window saying "Please wait 20 seconds while a new copy of your application is downloaded" or something, with an hourglass so they know something is going on...
