[RESOLVED] Inno Setup: Remove registry setting when uninstalling

[Chris001]

Hi, my application has an option to start it when Windows starts.

If the user has set that option and uninstalls the application, the value will remain in the registry.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Name: Application name
Type: REG_SZ
Data: C:\Program Files\Microsoft Visual Studio\VB98\Application\Application.exe

How can I check if my app has been added to the Windows startup and remove it if it exists?

I found out it works like this, but I'm not exactly sure what code I need in my case.
The registry is not something to mess around with, so I'd like to be sure.

Root: HKCU; Subkey: "Software\My Company\My Program"; Flags: uninsdeletekey

Problem solved. This is how it should be done.

Root: HKLM; Subkey: "SOFTWARE\Microsoft\Windows\CurrentVersion\Run"; ValueType: string; ValueName: "ApplicationName"; Flags: dontcreatekey uninsdeletevalue
