Aäron thought my idea was worthy in

He said "Thanks for the feedback. Having the webinstall script detect existing archives in the same directory on the webserver sounds like a good addition to me".
Since there will be changes to the database too with RC2 which the upgrade tool should take care of, I don't look forward to a manual upgrade on four forums!
This is for those few of us who seem to have this difficulty and can't seem to resolve the webhost issue. I've read repeatedly information about this in the forum and what I've suggested may be a way to resolve it for those few of us who can't seem to get the upgrade program to operate the file upload part (and of course, it stops if it can't upload the files itself from SMF). But, we can put the files there for it ourselves by downloading them first to our home computer and then uploading them to each of our forum sites
along with the upgrade tool. This bypasses the webhosting issue whenever that's the problem for a few of us! All the upgrade tool would need to do is assess whether the archive is already in place to be manipulated and then no further uploading of files would be needed (since we did the heavy lifting with our own ftp program for the upgrade tool already). I know this is not what the upgrade program currently does, but it
could include this process, at least Aäron said he thought it would work! Please see the link in the first sentence above.
