I know the default command line to install applications on the unattended CD is this:

start /wait %systemdrive%\install\some_application\setup.exe /switch /anotherswitch

However, that just installs it onto the default path, which is C:\ (I'm guessing it puts the applications into C:\Program Files ??). Is there any way to change the install path? I like to install all my applications into D:\Program Files instead of C:\ (I keep the C:\ only for the operating system).

Is it as simple as substituting "D:\" wherever I see %systemdrive% ??

Thanks in advance!

start /wait %systemdrive%\install\some_application\setup.exe /switch /anotherswitch

the %systemdrive% you are referring to is where the installation is... it has nothing to do with where it gets installed to....

if it is an installshield installer and you have created an ISS file, just edit that file and change the installation path... otherwise some programs will let you specify an installation directory as a switch, but it depends on the program and the installer

I recall there's a couple of threads on Application Switches forum on how to populate D: (or whatever) as your system drive. Search for them.

[Unattended]
   ProgramFilesDir="d:\Program Files" 
   CommonProgramFilesDir="d:\Program Files\Common"

[GuiUnattended]
   ProfilesDir="d:\Documents and Settings"

Yes! This is one of the solutions.
