It's been a while since I've installed PHP for Windows, but every guide I've seen online tells me to set IIS to recognize .PHP files with php5isapi.dll. However, I can't seem to find php5isapi.dll anywhere after installing PHP 5.3.0 and PHP 5.2.10.
If I recall correctly it should be in C:\InstallDir
Am I missing something important?
FastCGI replaced php5isapi.dll
I would try downloading the binaries (rather than the installer). I found php5isapi.dll in those zips, but the .exe/.msi doesn't seem to install that dll.
Ironically, in the PHP 5.3.5 (Non Thread Safe, & Thread Safe) ZIPs you will find the "pws-php5isapi.reg" file. This registry key even mentions the php5isapi.dll file and setting it to the path of your PHP install. However, the ZIPs do not contain the dll file. Kind of an odd registry key to leave haging around if FastCGI is the only way to go now.
Here's an article on Microsoft:

I found php5isapi.dll
in archive
The path is: C:\PHP\php5isapi.dll
EDIT
A step-by-step guide.
The readme files in the install don't agree with the web pages they mention. The webpages mentioned have loose ends like this one. Well, anything but consistency, because us programmers love a challenge to maintain job security.
