I have a lyx 2.1.4 portable in my USB stick with a complete miktex, 1 GB size.
I tried to make a lyx 2.2 portable in the same way but some TEX errors appears. There are some dll libraries lyx can't find.
Maybe some of you know how to solve this errors.
I can send you this lyx 2.1.4 portable version (there is too big).
Thanks.
