Hello and welcome to Advanced Installer forums,
Thank you for your interest in Advanced Installer.
If you want to save your custom dialogs you can add them to
Repository. The "Move To Repository" context menu option export a dialog in the Repository directory, so you have the possibility to use the related dialog in another project. Also, please keep in mind that the predefined dialogs cannot be exported even if they are modified.
Also, if you have added a
control or a
control event on a specific dialog and you want to copy it on another dialog, then you can use the context menu "Copy" and "Paste" options.
Let us know if this helps, otherwise please give us more details about your scenario (maybe exemplify).
All the best,
Daniel
