Unable to install matlab properly.

Dear all, Hope you are doing great!

I am a newbie to Matlab & simulink. I had installed MatLab 2014b(64bit) & 2015spa (32bit) for different purposes. One for model development & other for FPGA development(2014b) It was running fine. recently from past 3 days, it is showing me errors. It says:

Undefined variable "rmimap" or class "rmimap.StorageMapper.getInstance.getStorageFor". Error in rmiml.RmiMlData/getAll (line 196) Error in rmiml.getAll (line 14) Undefined variable "rmimap" or class "rmimap.StorageMapper.getInstance.getStorageFor". Error in rmiml.RmiMlData/getAll (line 196) Error in rmiml.getAll (line 14).

I tried to open simulink & I see this error:

Warning: Undefined function 'coder.oneclick.Utils.isOnTargetOneClickEnabled' for input arguments of type 'Simulink.ConfigSet'. > In Simulink.Preferences/updateConfigSetCopy (line 29) In Simulink.Preferences.getInstance (line 59) In slinstallprefs (line 18) In simulinkrc (line 38) Warning: No appropriate method, property, or field 'registerTargetInfo' for class 'DAStudio.CustomizationManager'. > In slCustomizer/callAllMethods (line 44) In slCustomizer/refresh (line 73) In slCustomizer.staticRefresh (line 23) In sl_refresh_customizations (line 18) In slcustomize (line 4) In simulinkrc (line 48) Warning: No appropriate method, property, or field 'registerTargetInfo' for class 'DAStudio.CustomizationManager'. > In slCustomizer/callAllMethods (line 44) In slCustomizer/refresh (line 73) In slCustomizer.staticRefresh (line 23) In sl_refresh_customizations (line 18) In slcustomize (line 4) In simulinkrc (line 48) Warning: No appropriate method, property, or field 'registerTargetInfo' for class 'DAStudio.CustomizationManager'. > In slCustomizer/callAllMethods (line 44) In slCustomizer/refresh (line 73) In slCustomizer.staticRefresh (line 23) In sl_refresh_customizations (line 18) In slcustomize (line 4) In simulinkrc (line 48) Warning: simulink (blockdiagram.xml, line 394): Cannot find built-in block of type 'DiscreteFilter'.

If I open a model, I cannot run it.

I do not know how to handle this. I tried uninstalling all the versions & tried reinstalling. It does not help. Could anyone please help me to solve this problem? What should I be doing to make matlab alright on my computer?

Any answers will be appriciated,

Thank you in advance, Have a good day, Amith

Contact tech support. It is the easiest way to solve installation problems.

Thank you Adam. I did call them :)

Hi everybody,

We had the same problem suddenly appearing on an older 2015a install. MATLAB support supplied us with this code, that reset our system back to working order.

rehash toolboxcache
