This is a general error and be caused by a number of issues:
Please check the following before opening a service request for further assistance:
- Verify you have the correct version of tcl installed for Avalanche (8.4.13) and that the path is set in the GUI under 'Tools' 'Preferences' *This is required even if you will only be doing GUI testing with Avalanche without tcl. TCL install is located under 'Downloads' 'Spirent TestCenter' once logged into http://support.spirent.com
- If the above is correct close out the GUI, use task manager to also kill any javaw and tclsh process running, reboot the chassis/modules and re-try once the system is back up.
- If the problem persists, please contact support@spirent.com or open a service request via the web.
**For 3.90 users please ensure you have Avalanche build 3.90.2246 installed (not 3.90.2236 which has known issues running Avalanche on Spirent TestCenter)
