I am currently getting this error as well, with the following configuration:
Vectorworks: 2018 SP2 Build 401138 64-bit
Windows 10 Home 64 bit, up to date.
Traceback (most recent call last):
File "Vectorworks Cloud Services.py", line 5, in <module>
File "DCC.pyc", line 9, in <module>
File "PySide\QtGui.pyc", line 12, in <module>
File "PySide\QtGui.pyc", line 10, in __load
ImportError: DLL load failed: The operating system cannot run %1.
Web suggests this is a Problem with PySide importing OpenSSL and not finding ssleay32.dll and libeay32.dll
