Windows Installer can also perform an administrative installation of an application orproduct to a network for use by a workgroup.
An administrative installation installs a source image of the application onto the network that is similar to a source image on a CD-ROM. Users in a workgroup who have access to this administrative image can then install the product from this source. A user must first install the product from the network to run the application. The user can choose to run-from-source when he installs and the installer uses most of the product’s file directly from the network.
An administrative installation is invoked by running the installation from the command line with the /a option. You then select a network share point where a copy of the installation is posted as an administrative image. Users who have access to this administrative image can then install the product from this source. If users choose to run from source during the installation, then most of the application files will be used from the network.
Following is an example of a command line statement that runs an .MSI in administrative mode:
msiexec /a “C:\Files\Abc10EN.msi”
