Installed Python 3.5.1 windows x64 version and ended up having


which is outdated:

C:\Users\ismail>C:\Users\ismail\AppData\Local\Programs\Python\Python35\curl.exe -V
curl 7.37.0 (Windows) libcurl/7.37.0 OpenSSL/1.0.2d zlib/1.2.8
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp smtp smtps telnet tftp
Features: NTLM SSL libz

That is released in May 2014!

Also its insecure:

C:\Users\ismail>C:\Users\ismail\AppData\Local\Programs\Python\Python35\curl.exe -vvvv "https://www.g"
* Rebuilt URL to:
* timeout on name lookup is not supported
* Hostname was NOT found in DNS cache
*   Trying
* Connected to ( port 443 (#0)
* libcurl is now using a weak random seed!

I would be happy if you don't ship curl at all, or at least use a secure, up-to-date version from

I have no idea how you got a curl.exe there, but it didn't come from our installer.  Where did you get your 3.5.1 installer from?

Indeed, I am sorry! It was pycurl.
