But you can use it with other installers as well.
When you click on an Installshield created setup.exe, it will extract it’s contents to your TEMP directory. These contents include will include the program files (*.exe and *.dll). If they contain .CAB files like DATA1.CAB, you need to uncompress them to get to the actual content. There are utilities to do that here.
There are three reasons I can think of, where you might want to use this trick:
- You want to repackage the contents with another application packaging tool (ie. Wise)
- You want to examine the individual files
- You want to modify the setup command parameters.
