Downloading and installing cURL on windows 7

cURL is a command-line tool. This means it is run from the command prompt (in Windows) or terminal (in Linux or OSX) and its results are displayed in the terminal window. There is no graphical interface. So in order to use cURL, you first have to open a command-line window.


To setup cURL:
  1. Download and unzip 64-bit cURL with SSL: http://curl.download.nextag.com/download/curl-7.21.7-win64-ssl-sspi.zip
  2. Copy the curl.exe file into your Windows PATH folder. By default, this is C:\Windows\System32.
  3. Download and install the Visual Studio 2010 C++ Runtime Redistributable 64 bit here: http://www.microsoft.com/download/en/details.aspx?id=13523
  4. Download the latest bundle of Certficate Authority Public Keys from http://curl.haxx.se/ca/cacert.pem
  5. Rename this file from cacert.pem to curl-ca-bundle.crt.
  6. Move this file into your Windows PATH folder. By default, this is C:\\Windows\System32.
Run cmd.exe to open your command prompt.
  1. type curl  http://www.google.com
  2. type curl  https://www.google.com
For both commands, you should see a couple pages of the HTML source code. If you see this, cURL is up and running!
