RESOLUTION

Use the Offline Install procedures as described below for local or remote installations.

To perform an offline installation of the MiCC Server

1. Ensure that the MiCC Installation Executable (available at Mitel Online), MiCC Offline Installer Package (available at Mitel Online), and 7-Zip (http://www.7-zip.org/download.html) are available on the MiCC Server. 
2. Install 7-Zip
3. Run the MiCC Installation Executable and select the extraction location. By default this will be [Extraction Location]\MiCC_80\PFInstaller\PreReqs\
4. DO NOT PROCEED with "Deploy Enterprise Server" when the MiCC Setup Activates.
5. Using 7-Zip, extract the contents of the Offline Installer Package to [Extraction Location]\MiCC_80\PFInstaller\PreReqs
6. Now proceed with the installation through MiCC Setup.
