uncheck the components before followed by" Wireshark "installation 
double click to start the installation, has been using the default settings, only caveat is: previously installed "WinPcap" here need to check canceled 
so far we've had to build the basic components of GNS.
Second, to complete the installation of SecureCRT (be sure that no Chinese at its installation path, or prone to bug)
Run the corresponding system setup 
after starting the installation, set up in the following figure
