  there is a conflict with bytestring-0.9.1.10 and bytestring-0.9.1.7, I unregister the version of 0.9.1.10.

  ghc-pkg check, the message is: there are problems in package Win32-2.2.0.2 dependency ""bytestring-0.9.1.10...""
  the following packages are broken, either beacause they have a problem listed above, or beacause the depend on a broken package.
  Win32-2.2.0.2, haskell98-1.0.1.1 QuickCheck-2.4.0.1...
