ffxivinstaller.exe
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.cab
- data1.hdr (to my knowledge, this is some kind of “file index” for installshield installers)
- data2.cab
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.
