True, but that's not the question that was asked. You can create an uncrackable program, but unless you take measures to prevent it running on unauthorized computers it can still be freely copied and run elsewhere (the conventional definition of piracy). They are two separate issues.

I know of only 2 ways that I believe are proof against cracking:

1. Write the application in unmanaged C/C++. As a variation on this I believe John Ryan has been involved with a Chinese developer who has created a product that can convert a VFP application to an unmanaged C/C++ DLL.

2. Don't distribute the executable - provide it as a web service i.e. SaaS

I don't know the mechanism behind Molebox, ReFox etc. but if they don't convert to C/C++ I believe they are vulnerable. My understanding is any such product can be run in a virtual machine which is in debug mode, which allows complete examination of any aspect of any code running within it.

Some viruses use extremely advanced techniques to detect they are being run in a VM, in which case they take countermeasures. I don't know if MoleBox etc. are that advanced.
