How to delete a registry value?

Question

How can I delete a registry value ? I have tried to add the deletevalue flag to my [Registry] entry but after executing the setup, the value gets re-created.

Can anyone show me how to delete a registry value ?

I found a solution in this question. Except using deletevalue I've needed to specify none value for the ValueType parameter of my [Registry] entry. So, something like this:

[Registry]
Root:  HKLM; Subkey: "Software\Microsoft\Windows NT\CurrentVersion\Audit"; ValueName: "MyValueName"; ValueType: none; Flags: deletevalue;

On 64 bits architecture, you have to use HKLM64 instead of HKLM – Broken_Window May 29 '17 at 21:23
