Software pack problems

hi...I'm new at arm and keil. I had some codes which are written using Stdphd at  STM32F4XX_DFP ver.1.0.8.  when I want to use CubeMX ,software packs of keil is changing and it want to install DFP ver.2.14.0 . After that installation,   I can't use/complair my old codes.  I can use old code after uninstall 2.14.0. I want to know that it is possible to use 2.14.0 and 1.0.8 versions together at  same time.  And sometimes after uninstallation my codes  give error again like as  error:  #35: #error directive: "Please select first the target STM32F4xx device used in your application (in stm32f4xx.h file)"
