Simulink doesn't "run" + error 126

Hello,

I have issues with Matlab. Whenever I start the program, the notification "LoadLibrary failed with error 126: the module was not found" (actually: "Das angegebene Modul wurde nicht gefunden"). Now when I just don't interact with the window and keep on working, everything seams to be alright. I tried to solve this issue nontheless and did everything, which I was able to find in other topics in this forum

-> update of graphic card drivers, "OpenGL software renderer", "set(0,'DefaultFigureRenderer','Painters')"

but it didn't help. The installation was fairly recently, so I don't think that installing everything anew would be very helpful.

Today I also started Simulink with the tutorial "Simulink Onramp" but whenever I try to run a simulation, no time elapses and nothing appears in the "Training Assessment" field.

Both issues might be related, but I am not experienced at all with problems like that.

I have a Windows7 Laptop from Acer.

Does the LoadLibrary problem occur when you start MATLAB, or when you start Simulink within MATLAB?

Is there more to the error message?

The error message does not always occur at the same point in time. Sometimes it occurs right when my computer starts and sometimes only after I started Simulink and got to the actual simulation window.

I don't know, what excactly you mean with "is there more to the error message". But no other error messages are shown when operating with the program and all other applications (QTIPlot, Excel,...) work properly. This message only occured when I installed Matlab with Simulink.

You need Service Pack 1 for Windows 7.

I started having this very same issue after installing a windows update this afternoon. The error shows up as soon as I open MATLAB of any version (I tried 2014b, 2017a, 2018b, 2019b). How to solve this? I am using Windows 10
