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