Why do I get a Bundle error message after updating MATLAB?

111 views (last 30 days)
After installing a MATLAB update, I get a Simulink start up error message of Bundle#350.
I tried to install the same update on other computers and found that some of them worked, while others had various errors like Bundle#10.
How do I prevent these Bundle errors?
