Z and I Emulator for Windows provides 3270, 5250, and VT emulation, connecting to z/OS®, z/VM®, eServer™ i5, iSeries®, System i5®, zSeries, and ASCII systems. Z and I Emulator for Windows uses Microsoft Windows Installer technology for all installation procedures.

When the Z and I Emulator for Windows installation image is first run, it examines the target system and, if necessary, automatically installs the proper version of the Windows Installer service. Setup.exe is the bootstrap loader that calls the Windows Installer service (msiexec.exe) and launches the installation dialogs.

The following should be taken into account when installing Z and I Emulator for Windows:

  • In some cases, installation of Windows Installer triggers a reboot of the system. If you are required to reboot, upon subsequent startup you are taken immediately back to Windows Installer to continue installation of Z and I Emulator for Windows.
  • After Windows Installer has been successfully installed, if the installation of Z and I Emulator for Windows fails or is cancelled by the user, Windows Installer rolls back all partially installed Z and I Emulator for Windows files and returns the system to its original state.
  • You must be a member of the Administrator’s group to perform these installations.
  • Before you begin installation, make sure all other applications are stopped. If you are reinstalling Z and I Emulator for Windows or are upgrading Z and I Emulator for Windows, make sure that Z and I Emulator for Windows is not running before you start setup.
