Now M 2.6.1 works without problems, besides startup time - it lasts about 1 minute - quite long. misconfiguration of Qt5, and not old or missing drivers. I surmise that problem is the result of e.g. I installed M 2.6.1 WITHOUT UNINSTALLATION of 2.5. I installed M 2.5 - this version worked without any problems.ģ. I have unsuccesfully tried different solutions suggested in Internet: install graphics drivers (difficult, because last supported by Intel driver was developed for Windows7), install unsinged drivers, install DirectX 9,10, install Angle OpenGL libraries etc.Īfter the few days I have found temporary workaround:Ģ. My father in law has been using Mnemosyne for the few years on old Windows 10 laptop.Īfter installation of 2.6.1 version (with prior manual uninstall of 2.6) it started to display the same message. Subject: Re: 'Failed to create OpenGL context.'

The long startup time might be related to this issue as well.įrom: On Behalf Of 15 August 2018 23:20 I'll try to look if there are files left over from 2.5 if you install 2.6.1 on top of it. 2.5 is bundled with an older version of Qt.
