Multiple customers have reported that elMaster Design would not load correctly after installing security updates of Microsoft .NET Framework. Startup of elMaster Design would fail with an empty error dialogue. This problem and other similar problems in other software is the reason Microsoft have stopped distributing the .NET Framework July 2018 updates on Windows Update and are actively working on fixing and re-shipping this month’s updates. Further reading available at Microsoft MSDN Blog.
In future releases elMaster Design will detect this kind of problem loading resources and present a better error message.
If you experience negative behaviour Microsoft referr to the .NET Framework August 2018 Update. It resolves this advisory for all supported Windows versions.
