No, Sven. I run the files as is.

I had only 2 problems. The first, I think that was a conflict between my Antivirus updates and old msys instalation.

So I clean and install, msys64 again. Then I tried the instalation (12 hours ago) but finished with some warnings related with Latex.

I tried today again, and all seems to work fine.

OK thanks. Maybe I need to clean up more aggressively before re-trying...

cheers
