Unexpected error on startup of COMSOL pointing to "Could not load file or assembly 'cstextrenderer_wpf"
After installing COMSOL Multiphysics, I receive an unexpected error when launching it. Looking in the log file, it points to an issue with cstextrenderer_wpf as per below
2020-01-08T13:52:42.170+01:00 Could not load file or assembly 'cstextrenderer_wpf, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The specified module could not be found. 2020-01-08T13:52:42.170+01:00 at ComsolDesktop.TextRenderer.CsTextRenderer.Init(String distrDir) at ComsolDesktop.DesktopApplication..ctor() at ComsolDesktop.App.OnStartup(StartupEventArgs e) at System.Windows.Application.<.ctor>b__1_0(Object unused) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)
The solution to this issue is to manually run the installers for the Microsoft Visual C++ Redistributable Packages found in the ext directory on the COMSOL DVD image.
Do the following:
- Download the COMSOL Multiphysics 5.5 DVD image from the Product Download page
- Go to the ext directory.
- Run the files vcredistx64.exe and vcredistvc141_x64
- Start COMSOL Multiphysics again.
