Community MSI Extensions is a collection of MSI custom actions and WIX extensions that extend Windows installer, originally developed by Application Security Inc. for a large Enterprise product, and open-sourced in 2009. The project grew and continues growing incrementally implementing everything that WIX didn’t have out of the box. All custom actions and extensions are fully unit-tested.
This release is the first one off Github, adds some small features, a number of bug fixes and is built with Wix 3.5. See the CHANGELOG for details.
