It is also possible to launch Packager by selecting the Excelsior Delivery -> Create Project menu item of the right-click context menu of a file or folder in Windows Explorer.
To create a complete installation package for your application, you first add the executable(s) and other files to the installation, fill the required information such as product and company name. Finally, you build the Excelsior Delivery archives ready for deployment.
Using Excelsior Delivery, you may update the existing installations of your product with upgrades or patches.
To create such an update, you need a project file for the original package that was saved as "updatable". Those project files have extension “.eiu”. Click the Open button on the Packager splash screen or later by selecting the File/Open menu item and select the desired updatable project file using a conventional file dialog.
Packager then assists you in tracking differences between the original installation package and the files currently available on your system to include only added and modified files in the update. See Adding files using the Difference Tracker for details.
When creating updates (see Creating an update), Packager detects which of the application files are new or changed and enables you to include them in the package. Update packages ideally suit the following purposes:
So, if you simply add a few files, or recompile your application’s binaries from a newer version of the source code, update packages will work fine.
Note: if you intend to create an update comprising a new version of your application binaries, make sure that both original and new versions are built using the same developing system.
