Do I need to deliver VirtualizerDDK.sys (or some other *.sys) in installation package with my device driver?

The unprotected driver links to VirtualizerDDK.sys. Code Virtualizer removes this dependency during protection, so you do not need to distribute the file with the protected driver.

Recent versions also support macros defined in an x86, x64, or ARM64 assembly file. This method avoids linking the unprotected driver to VirtualizerDDK.sys.
