Building a custom MSI installer for Windows

You can white label the LimaCharlie installer for Windows by using an MSI wrapper. By going through this process you can not only brand the installer to show your name / details, but you can also make installation of the sensor easier for end users. We have provided instructions below on how to use a 3rd party tool called exemsi.

Prerequisites

1. An MSI wrapper application, such as the exemsi application referenced in the instructions below

2. A digital code signing certificate (optional, but highly recommended)

Without a digital code signing certificate the installer will show a warning that it is from an unknown publisher.
