MATLAB: Removing preferences for Matlab applications running in deployed mode (R2014a / MCR8.3 glnxa64)

deletedeployederasegetprefMATLAB Compilermcrpreferencesresetsetpref

I am running a GUI application in deployed mode on a linux system, which uses setpref/getpref functions to save data. Recently, it started to crash at startup and I have not been able to use it since then.

I suspect that the error is linked to the data saved in the preference and I would like to erase all of it and start from a clean sheet. As this is a compiled application, I don't have access to the command line to locate the preference file.

So, where are MCR preferences stored and how can I erase/reset them?

You can delete MCR cache files, the cache location may be /home/YOUR_NAME/.mcrCache8.3, or $MCR_CACHE_ROOT/.mcrCache8.3 if you set environment variable "MCR_CACHE_ROOT". Once delete the mcrCache directory, you can run your deployed application.

MATLAB: Convert HG2 fig files (R2016a) to HG1 fig files (R2014a and older)

If you used savefig() without using the non-default 'compact' option, then in theory the .fig files contain a duplicate copy of the data in HG1 format for use with earlier versions of MATLAB.

MATLAB: How to resolve issues associated with MATLAB Compiler Runtime cache corruption

Delete the “mcrCache” folder used by the application and rerun the application.The “mcrCache” folder can be located by executing the following command in MATLAB Command window:

mcrcachedir

Note that “mcrCache” folders have the form “mcrCacheX.Y,” where X and Y indicate MATLAB Compiler Runtime (MCR) version. The “mcrCacheX.Y” output by the above command may not correspond to the version of the “mcrCache” folder used by your application.

Delete the “mcrCacheX.Y” folder used by the application. If you are unsure of which “mcrCacheX.Y” is used by your application, delete all folders of the form “mcrCacheX.Y” in the parent directory of the location returned by “mcrcachedir.”

For example, on my machine, “mcrcachedir” returns:C:\Users\Username\AppData\Local\Temp\Parth\mcrCache9.8

But the parent directory “C:\Users\Username\AppData\Local\Temp\Parth” contains folders “mcrCache9.1” and “mcrCache9.8.” Once you delete the appropriate “mcrCache” folder(s), try rerunning your application.

Alternatively, try changing the location of the “mcrCache” folder by typing the following into the Windows Command Prompt:

set MCR_CACHE_ROOT=<accessible_directory>

Where <accessible_directory> is some easy-to-find directory that you have the permission to modify (e.g. the Desktop). Then rerun the application from within the Windows Command Prompt by navigating to its directory and typing the application name in the same Windows Command Prompt.
