It doesn't matter how good the protection is, if it's applied incorrectly.

@Legend-Modz-V1: I didn't have to unpack it to find the key.. ;)

Manual unpack - I would start by analyzing hmvruntm.dll but its a lot of work..

Unpacking is difficult, and different for every program
Doubt anyone actually unpacked this

But the method used to bypass the protection is above
You can use and debugger , the string is in plaintext

You can also use resource hacker and do a string search while it's running in memory

@Elena: No, I never said I'm going to do that. ;) I have absolutely no interest in DNGuard, as it is used only on crap Chinese software.
