First of all, sorry for so long without commenting on the forum.
In order to end the installation problems, a repository has been created on github to perform the installation through the Addon Manager. I leave the link here: https://github.com/davidmubernal/Mechatronic
Also mention that the documentation has been moved to the repository of github and in readthedocs
I hope I can get the time needed to correct the reported bugs as well as some improvements.
Thank you very much to all of you who have tried MW.
