Webstore, MATLAB won't open
MATLAB versions R2009b and R2010a have a known bug that prevents them from opening when connected to a VPN. Because a VPN connection is required for the MATLAB Concurrent License due to campus firewall restrictions, the Mathworks workaround solution is to install version R2009a or earlier. Note that this only affects the Matlab versions listed above. If you are using a newer version of Matlab you should not be seeing this problem.
MATLAB won't open even though the process MATLAB.exe is running in task manager.
