PACE Suite provides a handy and fully-equipped MSI Editor tool, which enables you to:

• Manipulate contents of an MSI in a convenient tree-like interface.
• Import any resources.
• Edit and manage Custom Actions.
• Integrate scripts into your package.
• Create patches (MSP).
• Use a smart and advanced MSI database editor, with formatted string autocompleting, Excel-like formula bar, row reference tracking, and more.
• Handle upgrades easily – just let MSI Editor know which MSI’s you want to upgrade at a runtime.
• Undo-redo any changes to the opened file and highlight them in the MSI tables.
