Inno setup uninstaller doesnt delete rewritten registry values

Inno setup uninstaller doesnt delete registry values when they are rewritten by other program although the values stay the sames as inno setup wrote them when installing. Any solution?

Solution

  • Did you try deleting registry in Uninstall method, rather than using the flags in registry section? Eg :

    procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
begin
  if CurUninstallStep = usUninstall then 
  begin  
   if RegValueExists(RegistryAccount, 'RegistryPath','RegistryValue') then
   begin
     RegDeleteValue(RegistryAccount, 'RegistryPath','RegistryValue');
   end;
  end;
end;
