Hello everyone. When i try to run SolidWorks i get error message "could not obtain license for Solidworks standard, cannot connect to license server (-15,10,10061)." Anybody knows how to fix this problem? I am trying to run SolidWorks 2014 SP2 on Windows 8.1 and i have SNL license that i got for educational purposes from college. Thanks in advance.
