Have Visual Studio Setup Project retain registry key on uninstall?

Question

How do I get a Visual Studio Setup Project to:

• create a registry key only if it doesn't exist
• not remove the key on uninstall

Answer 1

Right-click on the Registry key in the setup project and select Properties.

1) To only create the registry key if it doesn't exist, ensure AlwaysCreate is False.

2) To not remove the key on uninstall, ensure DeleteAtUninstall is False.
