• Spirent TestCenter
• Wireshark
• Generate Streamblock from Pcap
• TCL

Answer 1

• Install Wireshark
  • for version to decode Spirent Signature visit http://support.spirentcom.com
• Install Spirent’s Tcl version 8.4.13
  • from Spirent download page : http://support.spirentcom.com
  • or other version that uses tclsh.exe and not something like tclsh85.exe 
    • if you only installed Tcl 8.5.x (e.g., TCL 8.5.9 (configured for Spirent TestCenter Automation) from the CSC) then this only installs tclsh85.exe and it will not work
    • but if you simply make a copy of tclsh85.exe and rename the copy to tclsh.exe then it will work.
  • if other version being used, may need to edit the stcbll.ini file
    • Example: Edit stcbll.ini (located in Spirent Application folder)
      • [ThirdPartyConfiguration]
        wireshark="C:\Program Files\wireshark\tshark.exe"
        tclsh=C:\Program Files\Spirent Communications\ActiveActiveTcl\bin\
• Check Spirent TestCenter application Settings > Traffic tab to set path to tshark.exe
  • for example C:\Program Files (x86)\Wireshark\tshark.exe)
  • the application will also prompt you to input this automatically when you select Generate Stream Block
• As a last resort if it is still not working uninstall and then reinstall everything:
  • Tcl (this time be sure to use Spirent’s Tcl version 8.4.13),
  • Wireshark (this time use Spirent’s Wireshark),
  • Spirent TestCenter application (but only if the first two don’t solve your issue)

Answer 2

• Spirent TestCenter is looking for a tclsh executable to use to run a script and the error is indicating Spirent TestCenter is not finding it.
• So if  altering stcbll.ini doesn't work check the PATH environment variable and make sure it is pointing to a tclsh executable. 
  • It could be the one installed with Spirent TestCenter, for example:
    C:\Program Files (x86)\Spirent Communications\Spirent TestCenter 4.45\Spirent TestCenter Application\Tcl\bin
• Also, on some systems, the PATH in "System variables" is not used so the path the tclsh executable must be added to the "User variables"
