I pulled out some old code to work on a legacy project of mine and lo and behold I get “Error 29 fatal error C1083: Cannot open include file: ‘atlrx.h’: No such file or directory”. Not exactly a pretty error and worse, this file was part of the standard ATL includes.

So what the heck happened to my good ole’ friend? Well, the geniuses at Microsoft decided it would be better to sit on CodePlex. So, you can download it from here.

The library is called the ATL Server Library. Just download it, and set your include path in Visual Studio to point to it. Or get creative and copy the files into an existing include path in the program files folder(under the visual studio folder of course.

Happy Coding!
