Ed, contact your Symantec or Partner SE for this, they should be able to set you up.  If you don't know who that is you can contact your Purchasing group or the Symantec Inside Sales team who covers your geography. 

Hi Edwork,

Please be informed that the trialware version is not available on the symantec website. I do advise you to contact you reseller and ask for the trialware. If you do not have a reseller go to this website which is partnerlocator.symantec.com and choose a reseller.

Kind Regards,
