• Possible solution

 

• • Remove Matlab cache folder. The folder, by default it is at %AppData%\Local\Temp\<username>\mcrCache7.17
    1. mcrCache7.17 may be named differently depending on the installed version of Matlab compiler runtime
    2. This is how you can find the %AppData% folder on your machine.
  • If problem still persists, try changing Matlab cache location
    1. Create a directory where the location is writable, for example create C:\mcrcache
    2. Go to Control Panel -> System -> Advanced System Settings -> Environment Variables
    3. Under System variables, add variable name MCR_CACHE_ROOT with the directory path created on the first step as its value
