I have updated LyX2.2.0 to 2.2.1 on my PC under Windows 8.1. Now it is impossible to launch LyX. The following error message is returned :
lyx.exe - Erreur d'application l'application n'a pas réussi à démarrer correctement (0xc000007b). Cliquez sur Ok pour fermer l'application. I have also updated LyX on an other PC under Linux. LyX2.2.1 works in a similar way to LyX 2.2.0. *I want to signal a problem affecting both Lyx 2.2.0 and 2.2.1:* I have a very big document (~100 Mo Pdf mainly of text with ~ 15000 pages) which was originally written with LyX 2.1 . It takes more than *one hour* to open it with LyX2.2.0/2.2.1 and only a few minutes with LyX 2.1.5. Once open it is possible to work as usual on the document but the amount of time necessary to open it preclude any operationnal use of LyX 2.2.0/2.2.1
