The machines that host the products on which you want to install fixes cannot go outside your corporate firewall (that is, cannot connect to Empower).

You want to install some or all of the same fixes on multiple machines that are running the same operating system, and want to avoid the time required to download from Empower.

You want to store a specific version of each fix so you can install the same fixes versions on multiple machines over time. Empower provides only the latest versions of fixes, so the version of a fix that is available now on Empower might be replaced by a later version in the future. An image always contains the versions of the fixes that you downloaded into it. Software AG recommends creating images to ensure consistency across product installations over time, especially if you have a long fix verification and promotion cycle.

You want to make sure you can install fixes at any time, regardless of whether production servers are locked down or have special access controls.

Connect to Empower and download fixes from a list of fixes that are available either for any product you have licensed from Software AG, or for only products in a model installation directory.

Run Update Manager on an offline machine to generate an inventory of products in a model installation directory and of fixes that are already installed on those products, copy the file to an online machine, connect to Empower, and download fixes from the list of fixes in the inventory file.
