Question: I am attempting to use curl commands in a batch file I am writing. I have downloaded the latest curl executable and run it but I cannot use the command "curl" What steps should I take to use it correctly? The Command line still says

**"curl is not recognized as an internal or external command, able program or batch file"**

I am not interested in doing anything else with cURL

Answer: 
You will have to add the directory containing `curl.exe` to your `path`, probably the `bin` directory.
In Windows XP you can do this by:

1. Right click your computer and choose properties
2. Click the advanced tab
3. Click environmental variables
4. Find `path` in the list and add the path to your curl directory
**Steps to install curl in windows**

**Install cURL on Windows**

There are 4 steps to follow to get cURL installed on Windows.

Step 1 and Step 2 is to install SSL library.
Step 3 is to install cURL.
Step 4 is to install a recent certificate

**Step One: Install Visual C++ 2008 Redistributables**

[Download Visual C++ 2008 Redistributables.](http://microsoft-visual-2008-redist.en.lo4d.com/)

**Step Two: Install Win(32/64) OpenSSL v1.0.0k Light**

Also from <http://www.shininglightpro.com/products/Win32OpenSSL.html>
For 64bit systems
Win64 OpenSSL v1.0.0k Light
For 32bit systems
Win32 OpenSSL v1.0.0k Light

**Step Three: Install cURL**

Depending on if your system is 32 or 64 bit, download the corresponding\*\* curl.exe.\*\*
For example, go to the Win64 - Generic section and download the Win64 binary with SSL support **(the one where SSL is not crossed out)**.
Visit <http://curl.haxx.se/download.html>
**More specific Link:** <http://curl.haxx.se/latest.cgi?curl=win64-ssl-sspi>

**Copy curl.exe to C:\Windows\System32**

**Step Four: Install Recent Certificates**

Do not skip this step.
Download a recent copy of valid CERT files from <http://curl.haxx.se/ca/cacert.pem>
Copy it to the same folder as you placed curl.exe (C:\Windows\System32) and rename it as **curl-ca-bundle.crt**

**If you have already installed `curl` or after doing the above steps, add the directory where it's installed to the windows path:**

1 - From the Desktop, right-click **My Computer** and click **Properties**.  

2 - Click **Advanced System Settings** .  

3 - In the System Properties window click the **Environment Variables** button.  

4 - Select **Path** and click **Edit**.  

5 - Append **;c:\path to curl directory** at the end.  

5 - Click **OK**.  

6 - **Close** and **re-open** the **command prompt**
