ftp program

You should use an FTP program to chmod your files.  You can even do this while at the install page where it asks you to change those file permissions.  Just change a few in your FTP program, then refresh the install page, and they will turn from red to green.  Keep changing and keep refreshing.  You will get to all green.

Ignore this.  Sorry, it's late !!

Since you mention it, I thought maybe I could throw out a little something that perhaps might be of use to some.  Maybe not.

Hell yeah it's late.  Use putty, and copy and paste the command.  Zip - Bam - Done instantaneously.  And they change back the same way.

But my point was reference FTP itself.  I don't FTP at all anymore.  I used to use it, but I've been sniffed-out twice on port 21, and they mangle the pages on about 10 sites.  I'm lucky, as the credentials they used could have done a an r -rf and completely blown the system away through its own own rectum and made it chew its own tail off, if he meant to and knew how.  He had the authority, but didn't use it.  Would have been a complete ground up job of all kinds of software, CMSs, streaming video-chat, gigabyte, upon gigabyte of content data to move around.  And God help you if you don't have backups.

I was very lucky.  It was the same guy both times.  I'm sure, as it was the same nonsense code on every single page, that scrambled the pages in IE.  We didn't know about it for a couple of days, as we pretty much use Firefox most of the time.  IE is just for testing.  I learned the hard way.  And some of these site were production sites producing money.  Not just a few dollars, I mean money.

Port 22; no FTP.  You  are transmitting your name and password to everyone if you are using FTP on port 21.  Anyone can reach out and grab your login with really 0 effort.  Just a sniffer.  If you can run an FTP program, you can run a sniffer.  So the vulnerability factor is pretty high, as no special skills are required; only the desire to get FTP access to your machine.  Port 22 is secure, and you can configure most FTP applications to use port 22, so you can keep using whatever you have probably.

If you didn't know, you do now.  I hope this brief diatibe can help somebody doesn't know everything yet.
