PHP Manager for IIS fails to install

Question

I am trying to install PHP on IIS 8.

Every time I start the PHP installation, PHP installs but I get the follow error:

Answer 1

The setup program checks that the registry value HKLM/System/CCS/Services/W3SVC/Parameters/MajorVersion is >= 7. The value in the registry is 0xA, which I am assuming is the problem. For a workaround, change the registry value to 9 (or 8 or 7) and PHP Manager for IIS should install correctly. [insert standard disclaimer about editing the registry]
