I can't say which version number it was for me. But I know it had only one digit after the three. Maybe 1.3.6 or 1.3.9.
IIRC 1.3.17 was the first one with an msi installer. One with the sources and one jsut the binaries. I wanted a portable version or at least a zip file. I was never able to open the msi files to extract the files. After some time I figured out how the change the path in the config that I was able to run it with from a USB strick any drive letter on any computer.
The msi was one of the reasons I found frist XAMPP which was too bloated and then Apache Lounge.
I confess that I still miss the VC6, it ran on every windows computer without installing anything. Plug the USB stick or copy the files and one of my friends had a running apache on their computer for the next LAN party. Safer than open the windows share.
