CD-ROM, DVD-ROM, Single EXE, Single MSI, Internet, Web, One-Click, Network. These are all names of different release types in InstallShield. But, if you ask someone what the differences are, you may get different answers.
Here are the distinguishing characteristics of some common InstallShield release types:
Single EXE – all files are compressed into a single file, Setup.exe.
Single MSI – all files are compressed into a single file, which is a Windows Installer MSI database file (for example, wavepoint.msi).
CD-ROM/DVD-ROM – release targeted for a CD/DVD where all files are generally uncompressed. If you choose compressed, some of the files will be compressed into .cab files. The release may or may not include Setup.exe.
Internet/One-Click/Web – release that is optimized for Internet downloading. Users will launch it from an HTML page. It will include .cab files, but not Setup.exe.
Network – release that is optimized for a network installation, and may or may not include Setup.exe. The files can either be compressed or uncompressed.
As you can see, the only constants are Single EXE and Single MSI. The line is more blurred between all of the other release types.
