About the Action Execution Sequence

InstallAnywhere 2024 R2

Actions are executed in the order that they appear from top to bottom in a view on the Sequence page. You can use the up and down arrows to change the order of actions. The left and right arrows move actions out of or into folders.

Pre-Install and Pre-Uninstall actions are executed before their corresponding Install and Uninstall actions, which are executed before Post-Install and Post-Uninstall actions. Pre-Install actions are generally used to determine what to install on the target system or even if the installation should occur. Actions that are added to the Install sequence define what will occur on the target system, like creating folders, expanding archives, or moving files. Post-Install actions are often actions, like showing the ReadMe file or launching the application that was just installed, that require the existence of recently installed files. Actions that occur within Pre-Install or Post-Install are not automatically uninstalled.

Note:When an action is scheduled for the Pre-Install or Post-Install sequence, it may be executed more than once if an end user repeatedly clicks Previous and then Next repeatedly. This could cause several errors for actions that modify files, such as Modify Text File - Single File or Register Windows Service. To prevent such errors, it is recommended that you schedule these actions during the actual installation (within the Install sequence).
