On February 17, 2010 Flexera Software released a new version of their multi-platform setup authoring tool InstallAnywhere.

While Windows Installer setups had a maintenance mode and rollback capability from the beginning, similar functionality is now also available for cross-platform setups in InstallAnywhere 2010.

InstallAnywhere is available from the InstallSite Shop
