Thinapp needs repackaging after license update

Hi VMware Gurus,

A customer is evaluating thinapp and is running trial license.

Once the trial license expired the customer has requested another trial license which he got from VMware.

When he has tried to update the license, the customer says he needs to repackage the application all over again.

The question is can it be avoided... He is evaluation Thinapp 4.7.

Thanks in advance,

Rushdi
