MWArray assembly failed to be initialized

144 次查看(过去 30 天)
Hi,
I am running and developing this App for long time, I am using a .Net that was compiled with Matlab Library Compiler.
Suddenly today the App stoped working withe the message:
---------------------------
Matlab Error
---------------------------
Error initiating Matlab Library System.Exception: MWArray assembly failed to be initialized ---> System.Exception: The MATLAB Runtime instance could not be initialized ---> System.ApplicationException: The MATLAB Runtime instance could not be initialized
segv - SEVERE ERROR
at MathWorks.MATLAB.NET.Utility.MWMCR..ctor(String componentId, String componentPath, Stream embeddedCtfStream, Boolean isLibrary)
--- End of inner exception stack trace ---
at MathWorks.MATLAB.NET.Utility.MWMCR..ctor(String componentId, String componentPath, Stream embeddedCtfStream, Boolean isLibrary)
I tried to recompile, reinstall the real time engine install previous version and still getting this message.
I am not sure what changed. I installed the App in a different computer and no problem at all.
Your help will be greatly appropriated.
Thanks
Sharon

Your MATLAB Runtime cache folder might be corrupted.
Delete the cache folder.
%TEMP%\USER\mcrCacheX.X
If your Windows account is usera and MATLAB Runtime version is 9.3 (R2017b),
the above folder would be
C:\Users\usera\AppData\Local\Temp\usera\mcrCache9.3
After deleting this folder, you can freshly launch your compiled application.

Issue occured on Matlab Runtime 9.8 as well. But these steps resolved it. Thanks!
