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 OpenEdge product components and subcomponents.

For a description of the steps to follow when installing OpenEdge, see the OpenEdge online installation help system. Online help is accessible from all supported platforms in Windows and on UNIX.
