The Vulkan version is determined by multiple factors. It depends on what your device supports, the header you're using and the api version you request when creating your application. The "installed" version is either the SDK you're using or (one of) the runtime(s) your driver did install.

Checking via command line can be done using the vksjon_info tool from the LunarG SDK.

Checking via code (no matter what language, as long as you got headers) can be done by querying device properties via vkGetPhysicalDeviceProperties. The apiVersion member of the VkPhysicalDeviceProperties struct contains the maximum supported version for that device. Just shift the bits or use the version macros from the headers to get a humnan readable version (major.minor.patch).
