I managed to get my setup working. Here are the notes I made at the time: It appears that the problem was a 64-bit/32-bit confusion issue. The problem goes away entirely if I follow the procedures below: 1. Open a cmd terminal. 2. Type CALL %VSFORPYTHON%\vcvarsall.bat amd64 [where VSFORPYTHON is the appropriate Virtual studio folder] 3. Launch my IDE from that cmd environment rather than using a windows shortcut.
