Looking for InstEd? Use a modern, up-to-date, free MSI editor instead.

The free Master Packager Community edition offers all the MSI and MST editing capabilities people used in paid InstEd Plus (not available for years) – and more – with active development and support.

Very slick MSI repackaging app. And most of it is free! What is not to love? For me, this replaces the free InstEd, which has not been updated for years, but I still loved. And it plays very nicely with PSAppDeployToolkit.

Very impressed with the free community edition of Master Packager. May well replace the ancient InstEd Plus as my day-to-day package editor. The full version with repackaging capability is also competitively priced.

Master Packager community edition was a recent find for me, and so far it's done everything I need for generating MST's and inserting my files that I need with the free community edition.
