Hi,

I get the following error when attempting to run my script:

%Error using matlab.internal.editor.eval.FileInfo
Java exception occurred:
java.io.IOException: java.lang.RuntimeException: Internal Exception in reading MLX file : fl:filesystem:AccessDenied
  at com.mathworks.services.mlx.MlxFileUtils.writeCode(MlxFileUtils.java:204)
Caused by: java.lang.RuntimeException: Internal Exception in reading MLX file : fl:filesystem:AccessDenied
  at com.mathworks.services.mlx.MlxFileUtils.nativeWriteMlxFile(Native Method)
  at com.mathworks.services.mlx.MlxFileUtils.writeCode(MlxFileUtils.java:202)
Error in matlab.internal.editor.eval.TmpFilePath.get
Error in matlab.internal.editor.evaluateCode
Error in matlab.internal.editor.evaluateCode

I'm trying to figure out what is causing this error, please help!

I meant copying the file into a folder that's completely independent of the cloud.

It may be a red herring but the error message and your initial comments would suggest that something is opening the file at the same time as matlab. The only thing I can suggest is looking at which processes try to access the file with something like process monitor.

I'm tempted to believe it may be related to the fact that each desktop I have owns a different iteration of matlab (2016a, 2017b and 2018a). Perhaps by going between each one I may triggering java run time errors.

Because some path settings are migrated from older version to newer version. Those paths that point to 2017a rather than 2017b or higher will cause these access errors.
