During the installation of Apache2 I got the following message into cmd window:
Installing the Apache2.2 service The Apache2.2 service is successful
Run the httpd.exe from the command line, as Tim mentioned. The path to PostgreSQL changed, nothing else was running on Port 80 and I didn't see anything in the error.log file.
I clone my boot drive/partition once the base is setup so I don't have to spend three days installing and retweaking everything. Turns I had reinstalled my WAPP stack and used very specific names/versions for PostgreSQL. Windows will not return a specific error message unless you run the command from the command line.
