Disk Space Requirements

Installation of Z and I Emulator for Windows to a drive other than the Windows volume (the drive containing the Windows folder) may still require as much as 180 MBs of available free space on the Windows volume. This is due to the installation of files to the Windows and system folders, as well as the caching of the Installer database by the Windows Installer service, and the use of temporary disk space by the Windows Installer service during the installation.
