Applies to: ZWCAD 2017; ZWCAD Classic
In some situation, user want to activate license by license manger of Classic or 2017 and find that it takes a really long time, and finally fails.
It is caused by the OS limit license file generation, even though turn off the firewall or anti-virus, still happens.
In this case, please try to use license manager of ZWCAD 2012(ITC). It has more permission to pass the detection from OS and can help user to activate successfully.
