Delete registry key during uninstall

Question

I have a simple C # application that allows users to specify that it should (or should not) run on Windows; he does this by installing (or removing) the registry key (namely ... \ Software \ Microsoft \ CurrentVersion \ Run \ MyApplicationHere).

I am using the VS installation project to create an installer for this program. I do not want the installer to create this key; it should be created only when the user selects a parameter from the program.

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

Answer 1

The registry table is designed for this:

See, in particular, the description “Name”:
If the Value column is Null, the rows shown in the following table in the Name column have a special meaning.

- the key is deleted, if present, with all its values ​​and subsections when the component is deleted.

Answer 2

"", "" → "", . ( → ) AlwaysCreate, DeleteAtUninstall Transitive keep AlwaysCreate to false, DeleteAtUninstall - true Transitive Done..

Answer 3

Try creating a custom delete action to delete the key. Not very "built-in", but it's just a couple of lines of code.
