In a basic MSI project, I want to create a subkey in HKCU\SOFTWARE\Policies (the whole key is HKCU\SOFTWARE\Policies\Microsoft\Edge\ExtensionInstallForcelist (*) ) Then I want to set a value and its data under this key. 1°) I create the subkey within a Component. this step is good: the subkey is well installed. 2°) Then i set the value by an InstallScript Custom Action. the function code contains a call to RegDBSetKeyValueEx with the specified key (*). This step runs into an error: The problem is that RegDBSetKeyValueEx fails to update the data with error ACCESS_DENIED. The custom action is run in deffered context. Can I call directly the Win32 API RegSetKeyValue with my script  instead? https://docs.microsoft.com/en-us/windows/win32/api/winreg/nf-winreg-regsetkeyvaluea What is the prototype to declare in my script ? Thanks. ... View more
