You need to install python-2.7.6.amd64.msi first,
you also need to add python directory to your system's "path" variable.
After installed python, install those packages:
PyQt4-4.10.3-gpl-Py2.7-Qt4.8.5-x64.exe
matplotlib-1.3.1.win-amd64-py2.7.exe
pycurl-7.19.3.win-amd64-py2.7.exe
python-dateutil-2.2.win-amd64-py2.7.exe
pyparsing-2.0.1.win-amd64-py2.7.exe
numpy-MKL-1.8.0.win-amd64-py2.7.exe
six-1.5.2.win-amd64-py2.7.exe
If you can not find some 64bit packages from their official sites,
try to find it at

just open a command prompt and cd pcryptsy directory,
