# 2.5.3.2 PHP for Windows

Starting from release 1.8.0, full PHP install is no longer supported by *Microsoft's Web Platform Installer* as the extensions are not included by default***.***For this reason, install PHP using the Zip file install. The installation steps are as below.

For additional information about PHP for windows you can go to Microsoft's website at [PHP](https://www.php.net/downloads.php)

### PHP Installation Steps

1.

- click on the download link [**latest non-thread-safe Zip file package**](https://www.php.net/downloads.php)**.**
- click on [**Windows downloads**](https://windows.php.net/download#php-8.3) under current stable version. 
- Download the **zip** file under VC15 & VS16 **Non Thread Safe**section.

Make sure to select the link for non-thread-safe zip file for the install.

2. Download the **zip** file under**VC15 & VS16** **Non Thread Safe**section.

Once the download has finished, extract the files to directory on your IIS server. (for example, `C:PHP`) 

The VC15 and VS16 PHP builds require that the Visual C++ Redistributable for Visual Studio 2015-2019 x64 or x86 be installed. Make sure you have the install.

3. Once the PHP files are extracted, copy the php.ini-production file to php.ini
