You can automate the deployment of the MI client tools (MI:Admin and MI:Toolbox) by using the .msi packages contained within the installation CD.
MI:Admin path: InstallationCD\InstallationManager\MIAdmin
MI:Toolbox path: InstallationCD\InstallationManager\MIToolbox
The following command will install MI:Admin in silent install mode.
msiexec.exe /i AdminInstaller_x64.msi /qn
Please note: This command will need to be run as Administrator.
For a full list of msiexec switches please run msiexec /? from a command prompt.
Please email support if you require further assistance.
