Hey 

I installed Ansys 2019 R2 on my laptop, it works normally. But yesterday when I open workbench, I get a error as following. Also all old files cannot open.

 

An unexpected error has occurred: The following required addins could not be loaded: Ans.SceneGraphChart.SceneGraphAddin. The software will exit.

--- System.AggregateException: The following required addins could not be loaded: Ans.SceneGraphChart.SceneGraphAddin. The software will exit.

--- System.DllNotFoundException: Unable to load DLL 'SceneGraphChart.Components.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

   at Ans.SceneGraphChart.Engine.Ans_SceneGraph_Bootup(Object p_iConfiguration, Object p_iErrorHandler)

   at Ans.SceneGraphChart.Engine..ctor(IConfiguration p_config, IErrorHandler p_errorHandler)

   at Ans.SceneGraphChart.SceneGraphAddin.Load(AddinLoadContext context)

   at Ansys.Core.Addins.AddinManager.setupAddin(String path, String name, AddinBase addin)

   at Ansys.Core.Addins.AddinManager.LoadAddin(String name, String path)

 

I have tried to update my graphic driver nut still not work. Anyone has idea on that?

If it worked yesterday, try reset configurations by using the following command in CMD Prompt

move "%appdata%ansys" "%appdata%ansys.old"

If this doesn't help, it could be that there was some Windows update installed that broke some of your Windows system files. You may need to revert back or uninstall this update.

Thanks for your advice.

I tried this, but still cannot work. I wonder if reinstall ansys could work?

It depends on the cause of the issue. But you can try re-install and see if that helps.
