I've checked their official website and this is what it says related to availability and compatibility:
- Interfaces: Native C/C++, .NET wrapper, Java wrapper
- Operating Systems: Windows, Linux and Android(*)
As you can see MorphoSmart SDK supports, Android which means that you probably downloaded something different. Also, the SDK doesn't appear to be available for download from the SDK's page which means that you'll have to get in touch with the developers for this process.
