It seems that FIPS 140 compliance is enabled on your computer. This will disallow non-FIPS certified algorithms to be executed.

E.g. Microsoft's SHA1Managed is not certified, while SHA1CryptoServiceManager uses CryptoAPI and should be ok - it really depends on platforms and versions.

The easy workaround is to turn off FIPS compliance on your computer (see notes for registry keys).
