EDIT: IT NOW WORKS! FOR ITUNES 5. WITH SCREENSHOTS.

I take no credit for anything, just an expansion of rikgale's guide.

Putting everything in a central area, easy to refer to.

This guide will make a 7-zip switchless itunes 5 installer.

Visual


Preparation
get the following:
- itunes installer from apple [http://www.apple.com/itunes/download/]
- 7-zip [http://www.7-zip.org/]

these are available in an archive in the post below
-7zS.sfx
-config.txt
-its.cmd
-makeinstall.cmd

Steps

1. Install a clean install of itunes using the apple installer. Install 7-zip.
2. Configure your itunes and quicktime settings as desired.

OPTIONAL STEP FOR PREFERENECES
You need to get 3 files for your preferences. Get the files:


The first two files have the same name, so we rename them to APiTunes.pref and LOiTunes.pref respectively.

3. Rename the setup you downloaded from Apple, to its.exe. We do this to ensure the filename is less than 8 characters.

4. Place all this in an empty directory.


5. Select all the files except config.txt and makeinstall.cmd. Right click on any file, and select "add to archive...". Change the compression setting to Ultra, and the file name should be its.7z.

6. You can now delete the still selected files, leaving makeinstall.cmd, config.txt, 7zS.sfx and its.7z in the directory.

7. Now run makeinstall.cmd.

8. You now have a file named iTunes.exe that is a silent installer of itunes 5.

mirrors welcome.

edit: updated for iTunes 5.0

k, well first off the itunes.pref should technically be the same, so maybe copying itunes.pref to both locs would be something to add to its.cmd...also, you cannot 7z all the files you listed because you have an archive in an archive...what you need to do is extract its.7z and then select all the files and 7zip that up. so the final its.7z should have quiktime.qtp, itunes.pref, its.cmd, and all the files that are in its.7z. then it might work...if not then it could be something in the 7z file...also, post your cmd file.

it's in post no.2.

will try building it again.

so i dont have to put anything in my RunOnceCmd.bat or whatevers it called? how is this executed?

Like Evilvoice said - if you 7zip the its.exe, it will not work.
From your its.cmd:

This is looking for 'its.exe', not 'its.7z'. Basically, dont 7z up the 'its.exe' - put the original exe file into the archive with all the others files, archive the whole lot as 'its.7z', then run your makeinstall.cmd. (ie ignore steps 5 & 6)

SP

u still need to add one line. just call the exe. i don't use RunOnceCmd, but i think it is:



substitute your own path to the file.

updated for itunes5.

screenshots coming very soon.

i hope a mod can edit the thread title.

edit: screenshot up.
