Matlab Compiler error: mclmcr initialization failed
显示 更早的评论
After compiling a appdesigner window to a desktop app I can't install it and run it.
I allways get an error window with the text "mclmcr initialization failed"
I tried compiling the app from the appdesigner tool and from the Application Compiler app both with "runtime downloaded from web option and with runtime included in package option active and the results were the same in all situations.
Do you have any thoughts about how to fix this issue?
The app uses the following licences:
distrib_computing_toolbox
image_toolbox
neural_network_toolbox

I realized that some DLL libraries are being loaded from the 'System32' folder instead of the <MCRroot> directory.
I tried moving the "MATLABWebAppServer.exe" from where it is currently to the following location and it worked for me:
C:\Program Files\MATLAB\MATLAB Runtime\v97\bin\win64
Then, launch the application from that location to try and force it to use the correct DLL files. Before launching, it would also be worth trying to delete your MCRCacheroot folder. The directory for this folder can be found below:
C:\Users\<username>\AppData\Local\Temp\<username>\mcrCache9.7\
I hope these steps will guide you towards solving the issue.

Thank you for your idea, it has been enlightening! I've found that you can simply copy the 'v97\bin\win64\mclmcr.dll' file into the same directory as the '.exe' application, and the application will run!
