I got bored and decided to add Photoshop to my unattended CD _OSXP_. I ended up with an installer with 48 mb 7zipped, not bad considering i had Paintshop Pro taking abt 73 mb on my CD. had to do some msi editing first 🙂 anyway if you want a similar install you could try

1. download modified photoshop.msi – Helpcenter / Bridge and some unneccesary files have been removed

2. create file Abcpy.ini with the following

;***************************************************************
;Adobe Installer External Configuration File: Abcpy.ini
;***************************************************************

;***************************************************************
;Main Section
;The (Product) key is a required key
;***************************************************************
[MAIN]
Product=Adobe(R) Photoshop CS2
AbcpyVersion=2.0

;***************************************************************
;OEM Installation Options
;***************************************************************
[OEM Install]
SERIALNUMBER= xxxx-xxxx-xxxx-xxxx-xxxx-xxxx

USERNAME=
COMPANYNAME=
INSTALLDIR=

3. put photoshop.msi in the photoshop installation folder

4. Make an admin install by typing in cmd prompt msiexec /a photoshop.msi

5 copy Abcpy.ini where the installation was extracted

6. make a 7zip installer
