Creating a Single Self-Extracting Setup File
InstallShield X—Express Edition
To create a single self-extracting setup file:
Select the SingleImage media type in the Build Your Release view.
In the property sheet to the right, set the Compress Media option to Yes. Now, any setups you build are compressed into one file.
If you set the Include Setup.exe option to Yes, the file generated by InstallShield is an executable (.exe) file. The executable file contains all the files needed to install the Windows Installer service, your Windows Installer setup (.msi) file, and all of your application files. If youdo
not include Setup.exe in your setup, the single file generated is an .msi file containing all of the logic and data necessary to install your application onto a Windows Installer compatible machine.
You can further compress your setup by using InstallShield's complimentary PackageForTheWeb.
就是在Media那里设置一下
