Why do I receive the Warning Mesage "Toolbox Path Cache is not being used" when I use the MATLAB Compiler 4.0 (R14)?

Sometimes, when I run a stand-alone application created using the MATLAB Compiler, I receive a warning message similar to the following:

 Warning: C:\Program Files\MathWorks\MATLAB Component Runtime\v70\toolbox\local\pathdef.m not found.

 Toolbox Path Cache is not being used. Type 'help toolbox_path_cache' for more info.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

Note that this is a benign warning message and should not affect the compilation or execution of the program.

One way to work around this issue is to create a blank pathdef.m and place it in the directory

$MCR\toolbox\local\

where $MCR is the directory where the MATLAB Component Runtime (MCR) has been installed on your system.

Another way to workaround this issue is to create a new copy of startup.m and disable warning messages as follows:

   warning off

Ensure that the startup.m file is on the MATLAB path.

Note that after making the modifications, you will need to recompile your application.
