I really doubt you will be able to get the 22.214.171.124 FDM adapters for HFM. As the premier support is end for the version already.
If you are planning for an upgrade a SR ticket will help you to get the needed adapter, since its a practice VM, why not playing around on latest version?
Classic FDM is gone as a product and has now been replaced by FDMEE. You are probably wasting your time practicing on that version as there are likely to be no new instances of that version being implemented in the real world. I'd strongly advise that you spend any time you have learning FDMEE
