Hi,
You can try a couple of things to fix it:.
1.Type the following command in MATLAB command prompt to see if you have the connector installed:
which -all connector
2. If you don't see any connectors installed, run MATLAB as administrator and install the connectors.
3. Also there may be a possibility that the path to the connector folder is not added, try adding it manually.
