When you choose the Custom installation option, all mandatory products and subcomponents are installed, but you can selectively install the recommended and optional components and subcomponents on a product-by-product basis. A Custom installation provides more advanced users, for whom this method is recommended, a means to distribute OpenEdge components on different machines, the ability to select product components to suit their business needs, and allows for working around issues such as disk space limitations.

The mandatory, recommended, and optional components and subcomponents for each OpenEdge product are listed, by product, in the tables found in OpenEdge product components and subcomponents.
