Hello Jim,
In order to achieve what you want you can proceed like this:
- Go to "Install Parameters" page and enable "Run as administrator" option.
- Go to "custom Action" page and add the related registry backup script custom action under "Install Execution Stage" -> "Paths Resolution" action group.
- Add the restore and delete registry backup script custom actions after "Finish Dialogs Stage".
- Build and run your project.
Also, starting with version 9.4 of Advanced Installer you can achieve this using our persistence feature. You can proceed like this:
- Go to "Registry" page, select your registries key and from its context menu choose "Properties..." option.
- In the "Edit Registry Key" dialog ->
"Operations" tab enable "Preserve key content" option using desired condition.
- Build and run your project.
Let us know if this helps, otherwise give us more details about your scenario.
All the best,
Daniel
