That's less than half the price of the student version, so it's pretty obviously hacked. Before installing it you might want to think about what else the hacker might have done other than cracking the security. After all, why sell it for only $40? If the student version is $100, someone would surely be happy to pay at least that for the full version. Hacked software always carries the risk that a little extra "something" was tucked away into the installer. Or that "registration.exe" file.
