several applications (including the camera driver) with different installation routines.
The complete suite can be repackaged like this:
- Create a setup.iss file in the windows directory by running "setup.exe /r" from the software\instdata\<language> directory
- When trying to install the setup in unattended mode with the setup.iss created the installation fails.
Therefore I tried various modifications of the setup.iss and finally succeeded by changing these lines:
Component-count=4
Component-0=FVW
Component-1=RCW
Component-2=ZBEX
Component-3=WIA_DUMMY
to:
Component-count=1
Component-0=WIA_DUMMY
...which by definition should only install the driver but it actually installs the whole suite

- Another issue is that the installation source files must be in the root of the installation drive, as if they were on a CD (c:\software\...).
The main section of an Empirum script to run the installation could look like this:
[Application]
...
ApplicationDir=%ProgramFilesDir%\Canon
...
[Product]
--Set:Installation, DONTDELETE
[SET:Installation]
md c:\software
callhidden %system%\xcopy.exe "%src%\*.*" "c:\software" /S /Y /K /I
Cd "C:\SOFTWARE\INSTDATA\GERMAN"
Call "SETUP.EXE" /S
If DoesfileExist ("%App%\Camerawindow\camerawindowcomp.exe") <> "1" Then "SET:InstallationError" EndIf
deltree c:\software
The setup.iss must be in c:\software\instdata\german when running the setup.exe /s
A reboot after the installation is recommended.
After the restart a user without admin rights can connect a camera and the driver will install automatically.
