Created attachment 108811 [details] Screenshot of the error message - log in a user to Windows that has no admin privileges - start LabPlot 2.5RC2 -> Crash I attached a screenshot. It Qt5Widgets is to blame here. But I wonder about that because I got the same crash with RC1 that was built with Qt 5.6.2.
Created attachment 108813 [details] difference between original Qt 5.9.2 DLL (left) and the one from LabPlot I attached another screenshot. You can see that the Qt5Widgets is not the original one from the Qt Windows installer from qt.io. I guess the problem is a patch in the Qt that is delivered with Craft because I also had problems with this "patched" Qt. So my proposal is to try to compile LabPlot for Windows using the official Qt libraries. Here is the QtSDK part in craftsettings.ini that works for me: [QtSDK] ## For advanced users only ## Whether to use prebuild Qt binaries. Enabled = True ## The path to the Qt sdk. Path = C:\Qt\Qt5.9.2 ## The version of Qt. Version = 5.9.2 ## The compiler version, if you are not sure what to use, have a look into the derectory set in QtSDK/Path. ## The compiler must be of the same type as General/KDECOMPILER. ## If you are using mingw please make sure you have installed the mingw using the Qt installer. Compiler = msvc2015_64 I propose this because this bug is in my opinion a release blocker.
This bug vanished in the meantime. I'll keep it open until I could test that it is gone also with a build from Stefan.
