The "DLL load failed" message is from Python, but the rest is the text for the Windows error code, ERROR_BAD_EXE_FORMAT (0x00c1) [1]. The "%1" in the string can be expanded as the first element of the Arguments array parameter of FormatMessage [2]. But currently the code in Python/dynload_win.c uses FORMAT_MESSAGE_IGNORE_INSERTS and does no post-processing to replace the "%1".
I don't know why the Windows loader reported ERROR_BAD_EXE_FORMAT instead of ERROR_MOD_NOT_FOUND. Possibly it found another version of a dependent DLL that was corrupt or for a different architecture.
Note that the setup in this case is odd in that the package is installed in C:\Python27 instead of in the site-packages directory.
