Matlab probléma?

Windows újratelepités után ismét feltelepitetem a Matlab nevű programot de nem akkar működni és a következő hibaüzenetet adja! Szeretném ha valaki elmagyarázná, hogy miféleképen tudnám orvosolni a problémát vagy egy link is megfelel ahol le van írva. (Ha lehet akkor inkább magyarúl)
