Software installations can be managed. For example, a first installation package for installing a first software product can be received. The first installation package can include a first set of configuration files indicating a first default configuration for the first software product using a generic format. A second installation package for installing a second software product can also be received. The second installation package can include a second set of configuration files indicating a second default configuration for the second software product using the generic format. A configuration dataset can be determined from the first set of configuration files and the second set of configuration files by merging first configuration data in the first set of configuration files and second configuration data in the second set of configuration files. The first software product and the second software product can then be installed using the configuration dataset.
