Your current serial number will not work.</P> <P>If you have Desktop subscription, you will use the same serial number for 2013 version and it will display in your Autodesk Account.</P> <P>Please check <A href="http://knowledge.autodesk.com/customer-service/account-management/software-downloads/previous-versions/request-previous-version-license" target="_blank">Requesting a Previous Version License</A>.</P> Tue, 25 Aug 2015 02:41:42 GMT lynn_zhang 2015-08-25T02:41:42Z
