Can I upgrade to the latest version if I have a multi-user subscription for PC-cillin Internet Security 2006, 2007 or 2008?
If you have a current multi-user subscription for PC-cillin Internet Security 2006 (i.e. if your serial number begins with PxxP, where x represents any letter) and your license was provided by your company, contact your system administrator or human resources department, who will contact the appropriate reseller or account manager for you. Otherwise, prepare your Maintenance Agreement and Order Confirmation Letter (if you received any) and contact Trend Micro Consumer Support.
