Problem with FIPS Validated Cryptographic Algorithms
I wonder if FIPS compliance checking is turned on on your machine.Here is a post that I had written a while back that talks about turning it off and why you might be getting this error messages.Basically FIPS is a US federal government standard for security and encryption. Based on it, some encryption algorithms will not run on your machine, if your machine is running in FIPS compliance mode.Easy fix in that case is to turn off FIPS compliance checking. The right fix is to pick the correct encryption algorithm.

I have some hours looking for this answer.
I am using Win7 64 Bits, I just turn as Disabled this local policy:
System cryptography: Use FIPS 140 compliant cryptographic algorithms, including encryption, hashing and signing algorithms
On Control Panel ->Administrative Tools ->Local Computer Policy ->Computer Configuration ->Windows Setting ->Security Settings ->Local Policies ->Security Options
Enjoy it!!!
