I was trying to install Wordpress on my old Windows 2003 Server.
Here is the link with the installation instructions for Wordpress Windows setup.
After running the Web Platform Installer, that sets up IIS, MySql, PHP, etc.. it was time to setup Wordpress itself.
After that a error message appeared saying that sqmapi.dll was not found. Due to this error Wordpress was not installed.
My first attempt was to Google for this error. I found no relevant solution.
Here's what I've done.
I've searched My Computer for this sqmapi.dll. Search found one copy at the folder
C:\Program Files\IIS\Microsoft Web Deploy V3.
I thought maybe it was not on the search path for Windows.
So I went to My Computer Properties, Environment Variables, and added the path.
After reboot I tried installing Wordpress again.
Done!! Problem Solved By IT.
