Hi, I have upgraded both software, and I noticed first that LilyPond did not compile any file, but I had only the Frescobaldi preview.
I re-installed both programmes, and LilyPond gave me the error message that LIBFONTCONFIG-1.DLL and LIBFREETYPE-6.DLL were missing. I upgraded both DLL in the LilyPond folder and, since nothing happened, installed them in their Windows folders. Then I had the error 0xc000007b. The same identical thing happens in Frescobaldi with PYTHON35.DLL. Any suggestions? I tried to re-install them many times. Luckily, I have no problems with another computer with Linux... Thanks in advance! Francesco
