p is usually so close to 0 or 1 that you can't tell the difference, and is
the latter when they're managing to use a download method that
systematically corrupts LF bytes into CRLF pairs on Windows -- or vice
versa. Both change length.
Keep the context in mind! This is Windows, so that particular form of
download problem is depressingly common, and these are generally newbies.
"MD5" doesn't mean anything to them. I've "dealt with" hundreds of these
If you want to make a standalone .exe available, that's great, and I'll
gladly refer non-newbies to it the next time there's a downloading problem
nobody can figure out (so please post a URL). The length check almost
always settles it, though; switching to a different download method then
almost always solves it; and I never see such reports from non-Windows
