Can't find the resource file 'toolbox/l​ocal/simul​inkrc.m'

I can't use simulink and there is followng Error:

Warning: Can't find the resource file 'toolbox/local/simulinkrc.m' needed by

'/Applications/MATLAB_R2019a.app/bin/maci64/libmwsimulink.dylib'

> In start_simulink (line 19)

In connector.internal.fevalMatlab

In connector.internal.fevalJSON

i have the same problem, if you've found the solution please let me know

Actually there should not be an M-file directly in the toolbox\local folder. Therefore it would be useful if you explain any details about the situation in which this problem occurs.

[Fernando Hurtado Garcia-Huidobro]

I have the same problem, how did you fix it?

[Jan]

Maybe you can explain the problem with more details?

I have the same issue, I just installed Matlab+Simulink 2019b under Window 64b and when I open a .slx model or when I launch simulink by command line it says:

Warning: Can't find the resource file 'toolbox\local\simulinkrc.m' needed by 'C:\Program Files\MATLAB\R2019b\bin\win64\libmwsimulink.dll'

Answer from the support (which worked):

"This warning indicates that MATLAB was unable to detect a core installation file required to run Simulink. There are a couple of things which can cause this; the most common source of error is if MATLAB's search path wasn't successfully updated upon your initial attempts at installing. To resolve this issue, enter the following three commands into MATLAB, one after the other;

>> rehash toolboxcache

>> restoredefaultpath

>> savepath

Then, try and access Simulink again."

I tried

>> rehash toolboxcache

>> restoredefaultpath

But I get the following error on doing this:

Error using restoredefaultpath (line 41)

System error: Standard CSHRC script not found.
