Runtime is the version of the CLR (or .NET framework) the DLL needs (usually as a minimum), version is the DLL‘s version.

So long as you have the minimum runtime installed, it should be usable. However as a general rule it is usually best to select the latest version of the library for the latest runtime support etc.
