This is not a standard InstallShield installer (at least to my knowledge) but seems to a self-extracting executable and then some form of InstallShield executable.

If you only care about the .cab files (which can then be read with your usual installshield libraries/tools like unshield) then they are contained right in the executable, uncompressed.

To find them, simply find the needle string “Disk1\{FileName}” where FileName is the cab filename. They are as follows:

  • data1.hdr (to my knowledge, this is some kind of “file index” for installshield installers)

They are simply put right next to each other in the executable, so if you follow that order you’ll find each of them quite easily.
