I am curious as to how you got the admin install to work I cant get it to run. When I try to run the installation from a script it fails to find the data1.cab file and then prompts to retry or cancel. This method would prove to be very useful if I could get it to work. The source size is reduced to 130mb when compressed with 7zip. I am running it with an AutoIt script but it would seem that the installer itself needs to be altered to keep it from checking for the data.cab file. But the .msi file itself runs fine when I just double click on it. Here is my AutoIt script if anyone is interested. The .msi has been renamed. RunWait("msiexec /qb /l* cs2-log.txt /i adobecs2.msi") ;Activation WinWaitActive ( "Adobe Photoshop Installer","" ) ControlClick ( "Adobe Photoshop Installer", "", "Button6" ) ;Activation2 Sleep ( 250 ) WinWaitActive ( "Adobe Activation","" ) ControlClick ( "Adobe Activation", "", "Button1" ) Exit ;EOF
