EDIT:
If you are having the "Insert Disk" error do the following:
a) extract the file and run the setup from the extracted files
b) Mount the file, and then copy all the files to a folder on your hard drive. Then run the setup from there.

Both these solutions do the same thing, copy all the files to your hard drive, where you can then run the "setup.exe" file and install this app.

Look in the crack folder for installation / activation guide.
