I don't think there's a way to get the information you want using only built-in environment variables. The information is inconsistent from Windows XP to Windows Vista/7, so I think your best option is to update your config file during installation where you can determine the OS and access other Windows APIs.
How to set config output to special folder (LocalApplicationData)?

Is there a way to set my app.config for my WCF service so that it outputs to the LocalApplicationData folder without having to hardcode anything?
%LOCALAPPDATA%
does not work in XP, and I need to support XP
I have found that shell:Local AppData
works, but I am not sure how to put this in an app.config
The next closest I can find is %APPDATA%
, but I do not believe this is not the same as LocalApplicationData
Worst case, I can (but would prefer not to) use code to do this (using the SpecialFolders directly), but I am not sure how to set this while keeping the rest of the settings configurable?

You can get it from Environment object.
string path;
path = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
Edit according to comment:
Now i understand. You can create your own environment variables to use as part of path in your config.
CMD:
set mylocalapplicationdata="somewhere"
or C#:
string name = "mylocalapplicationdata";
string value = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
Environment.SetEnvironmentVariable(name, value);
After this you can use %mylocalapplicationdata%
like other system variables.
You can set variable for one session (process), user, or machine (for machine you need admin permissions).

Alternatively you can use string like this:
%USERPROFILE%\Local Settings\Application Data
but this is for windows xp only.
