setup needs the next disk - mulitple instances on one machine problem

[Bin Ji]

I need to install one program multiple times on one machine, which is
not allowed by installshield, so I have to write a program
launcher.exe which remove the registry key and lauch the setup.exe, it
works fine if I run launcher.exe directly, but when I package them
into a single file using Package For Web, it removes the key, launches
the setup.exe, but weird things happenes when installshield begins to
extrace files to hard disk, it asks for data2.cab. The error message
is "Please insert disk 1 that contains the file data2.cab", I never
get this message by double click launcher.exe.

If I select "copy to folder" (which sets the defaultpath in the
project file), everything is fine, but I don't want to user to save
the cab files on their disk.

Thanks,
Bin
