David Nope I did not ignore any previous error messages. Something about Windows 10 and file permissions may be at the root. I had to run Fresco with Administrator Privileges in the past. One possibility that may shed some light is that I have installed Kaspersky Secure connection on both machines just before disaster struck (just to watch football).
I have since re-installed Lily from an old 2.19.56 installation package followed by Fresco again. This time when I run Fresco a new popup appears "running Lilypond this could take some time - nothing else happens. I will try running from a command prompt but as it stands "Lilypond does not exist" is the response. -----Original Message----- From: David Kastrup <d...@gnu.org> Sent: 06 March 2018 16:11 To: peter.gen...@sunscales.myzen.co.uk Cc: Lilypond <email@example.com> Subject: Re: Frescobaldi sudden failures on all machines <peter.gen...@sunscales.myzen.co.uk> writes: > I have been using Frescobaldi for years but today re-running old files > I see the following behaviour. > > > > The compilation proceeds for a while then halts with error > -1073741819.

I suspect this is just because failed assertions now make LilyPond abort with an error message and you previously ignored them (which was almost a given since distributed binaries of LilyPond completely omitted them). -- David Kastrup _______________________________________________ lilypond-user mailing list firstname.lastname@example.org https://lists.gnu.org/mailman/listinfo/lilypond-user
