What are the advantages to purchasing both Code Virtualizer and Themida?

Code Virtualizer provides a focused subset of Themida's protection. For an application with one EXE and several DLLs, you can protect the main EXE with Themida and the DLLs with Code Virtualizer.

Applying Themida to every binary adds more runtime code and consumes more resources. Code Virtualizer is lighter when you only need code virtualization.
