I wondered about it, but that would not explain why it fails in the first case
- perhaps the OP now knows what happened. Interestingly I get a different
error with the distribution binary for 2.5 - I get "Error 22" instead of "Errno
126", but the message text was same, so I assumed this was from a different
version and something had changed about how the errno is reported.
However, I checked the windows error codes and 126 seems to be the correct
error. The error code talks about bad command and the corresponding message
text reads "The device does not recognize the command."
