You don't need this since version 1.4. Use File\Open installer instead.

But if you still need manual unpacking, follow these steps:

  • Download Inno Setup Unpacker from Here
  • Run innounp.exe -x -m -dUnpacked path_to_installer to extract files and embedded resources from installer to new directory Unpacked.
  • If installer has compiled code it is extracted to unpacked\embedded\CompiledCode.bin

It is small game built as an installer. Try to recover code checking algorithm.
