Advanced Installer's Repackage Installation project allows you to create a project based on capturing an existing installation. For example you can repackage a legacy EXE setup into an industry standard MSI package.
For detailed help on how to repackage an existing installation package, please see the Repackager Tutorial.
Please note that the import features in Advanced Installer (the
Repackager, the Import MSI feature etc.) are intended to be used to get
a starting point for your installation package, not to completely
reproduce other installation packages.
The Repackager tool captures only the effects of the installation (the changes made on the system). If the original installation package executes custom code (programs, scripts etc.) then only the effect will be captured (registry entries, files and folders etc.).
Also, after repackaging an installation some adjustments may be necessary in order to obtain a working installation package.
