One defoxed app working well on win7x64 and XP.

Very good protection, because it recompiles a heavily altered exe rather than trying to create a tall wall around it. Obfuscation has an obvious effect, but Leonid also has added a new statement encryption using a variable key. From brief review to date it looks like a 6-byte key, so that's pretty good. You still can hook the project but now you need to disassemble the encryption and apply it to the p-code, or try to hook _execute just as you have to with VFP Compiler. Leonid has wrapped some sneaky stuff around that as well. ;-) So it's about as difficult as you can get unless somebody figures out a way to extract the keys to decrypt the statements, in which case you'll get access to the obfuscated code.

FWIW the statement encryption seems to slow things down slightly, especially compared to VC.
