Creating a Companion Install Package
Create a companion install package (also called a "companion database") to install any files that are not installed with Reflection.
Because companion files are installed independently of Reflection, you can upgrade the product without removing these support files. You can also deploy additional support files without re-installing the product. If, for example, you are supporting several business units that require their own customized configuration files, you can create a companion install package for each business unit.
Companion install packages support:
Companion install packages can be installed with any mechanism that supports MSI packages. The packages have no built-in user interface, other than the standard progress bar.
Note: Files typically included in companion databases include settings files, custom map files and themes, and access files (created with Permissions Manager).
