Hi Thomas,
This is what I do:
External function declarations:
function boolean SetEnvironmentVariable(ref string lpName, ref string lpBuffer) library "KERNEL32.DLL" Alias For "SetEnvironmentVariableW"
function boolean GetEnvironmentVariable(ref string lpName, ref string lpBuffer, ref ulong nSize) library "KERNEL32.DLL" Alias For "GetEnvironmentVariableW"
In the code below, there's a lot more than you need, like logging the set path to a txt file and other things, but just search on "SetEnvironmentVariable" and "GetEnvironmentVariable"
If you need more help, I can try to make a small sample app to achieve what you want, but I'm pretty busy right now, so it'll take me some time (like the weekend maybe).
