¡¡¡ I succeeded !!!
I have in my pen a portable Lyx, version 2.2.1 THE LAST ONE.
I want to share it with all of you, but don't know the way to upload it.
You can test it before sharing with the people (I want to test it in more computers to ensure that works: Windows XP, Windows 7, Windows 10...).
Tell me the way and you can enjoy with lyx.
It's a very huge compressed file, more than 1 Gb with miktex portable and Jabref too.
