Error installing PHP using Web Platform Installer on Windows 10/IIS 10

Question

I am trying to install PHP 7.1.1 on Windows 10, IIS 10 , using Web Platform Installer 5.0.

I am getting an error:

PHP 7.1.1 (x64) The product did not install successfully

Windows Cache Extention and PHP manager for IIS fail too, but I believe it is because of dependency on PHP 7.1.1.

I have already tried these:

1. set this key value to 8:

   HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/W3SVC/Parameters/MajorVersi

2. .Net 3.5 installed and WCF TTP Activation is enabled for .Net Framework 3.

What's the best way to get the PHP files working on my machine?

Answer 1

I ended up installing PHP manually . Web Platform Installer has many problems with PHP installation, and manual installation of PHP was fairly simple.

Answer 2

I ran into this same problem. I did the manual install and registered PHP manually. However, when I test PHP, it produces a 500 error. Have not been able to solve this in 3 days of research and trying various things.
