It is arguably as important to be able to examine and edit a Windows Installer package, but most would agree a basic requirement is a good MSI repackager. Repackaging works by taking a snapshot of a system before and after an installation is performed and configured in order to determine what changes have taken place. These changes are then repackaged into a new silent installation package suitable for internal deployment. A repackager differentiates mostly based on speed, but all employ a very similar user interface.
Repackager features to look out for include a good exclusion list editor, an ability to save snapshots for future use, lightweight installation or remote execution support to minimize change to target systems, and the ability to monitor processes in use during capture so as not to rely solely upon file changes to the system.
Additionally, you will find more modern repackagers capable of doing their work not just on your local computer, but on VMWare or Hyper-V virtual machines as well. Leveraging virtual machines is a practice many repackagers have long enjoyed, with built-in support it can be even easier to take advantage of the dynamic nature of virtual machines to speed your repackaging process.
This is one of many application packaging features covered here at AppDetails. When considering what features are important to you, we recommend you also contemplate the importance of a good GUI Editor, PowerShell Support, an MSI to App-V Converter, and other application packaging features.
