What is an administrative image (MSI) file?
Networking Issues
Uninstall and Maintenance Issues
If you elect to include all products in your deployment, the administrative image will be larger. You should select all products only when you create multiple deployments from this image and prefer not to use the installation disk. If there are products you rarely or never use, and you do not expect to create additional deployments, you should only select a subset of products.
You can still create a deployment at a later date, and include additional products, but you need to create a new administrative image. You need the installation media to do so.
