You should have these three files in your directory after unzipping:
INSTCHCK.EXE
INSTCHCK.DAT
FILE CRUNCHER.EXE

To make sure you have all the required dll files, you will need to run INSTCHCK.EXE. It will let you know if you have the required dll files. If not it will direct you where to go to get those dll files. If Install Checker notifies you that you have the required files, than you may exit the program and click on File Chruncher.EXE. Underneath the File Cruncher picture will be a button that says install. Just click on that and the program should be installed with in a few seconds.

You are now ready to chrunch your files.
