The Windows Installer is needed because your InstallShield is based on the Windows Installer technology. If it is not present on the PC, IS installs it first. WI files are not runtime files for IS. WI is a MS product.

>We created a setup.exe file, ran the setup on a PC, but after initializing the setup, Installshield gave a message about Windows Installer was installed and told us that the PC would have to be re-booted. The setup didn't even get to our application.

>Do client PCs need certain runtimes just to run InstallShield?

>A different PC ran the same setup.exe but didn't need to re-boot and the setup.exe performed as expected.
