The Linux version you have mentioned is not supported with ActivInspire and this could be the cause of the issue.
ActivInspire is only officially supported on Ubuntu 12.04.
Usually if the program doesn’t start, this could be related to your Flash/Java versions installed. Please check that these are up to date and re-launch ActivInspire.
Should this fail to work, we would recommend installing on a Ubuntu 12.04 operating system.
