There are export restrictions of some encryption algorithms there for windows versions of different languages/contries may have different crypto providers installed. The message you describe is displayed, when the "createrandomcryptkeys" method of the _cryptapi class fails to prepare random keys for the sample.

I tmight help to set the cProvidername property of the _cryptapi class to "Microsoft Base Cryptographic Provider v1.0"
