Remove registry key during uninstall

Question

I have a simple C# application that allows users to specify that it should be (or should not be) started with Windows; it does so by setting (or deleting) a registry key (namely, ...\Software\Microsoft\CurrentVersion\Run\MyApplicationHere).

I am using a VS setup project to create the installer for this program. I don't want the installer to create this key; it should only be created when the user selects the option from within the program.

Here is the issue: I would like the uninstaller to delete this key if it exists, preferably without resorting to any sort of hackery; if there is a simple "built-in" solution I would love to hear it. Thanks!

Answer 1

just right Click on Setup then Select View -> Registry, you can add a registry key to the list. The key has properties (right click -> Properties) AlwaysCreate,DeleteAtUninstall and Transitive keep AlwaysCreate to false, and DeleteAtUninstall to true and Transitive to true as well adn its Done..

Answer 2

The Registry table is designed for this:

See especially under the description of "Name":
If the Value column is Null, then the strings shown in the following table in the Name column have special significance.

- The key is to be deleted, if present, with all of its values and subkeys, when the component is uninstalled.
