I have trying to set a variable in the enviroment with no success, I have also looked aorund the forum for an example but with no help.

I guess it has to be
A_IncludeDir="%IncludeDir%"


But I'm not so sure if it is even possible to set a variable through Run.

It should work, but the variable is only valid for that DOS session, as it is when you do it manually. So this will work:

Do you mean doing a permanent change of the environment?
In this case, set doesn't do it: open a cmd box, set a variable, close the cmd, open a new one: the value isn't there.
You have the EnvSet command, but it has the same problem: only subtasks (like those ran with Run or RunWait) will see it.
The problem can be solved, but it depends on your system.

On old Dos-based systems (Win9x), you have to alter autoexec.bat and reboot... Actually, Microsoft provided an exe (WinSet?) doing a permanent change to the current system, probably using some voodoo.

On NT-based system (Win2k, WinXP), I believe these values are saved in the registry. I changed user and system environment with the System Properties dialog, monitoring with Regmon. Found:
HKCU\Environment\MyUserEnvironmentVariable
HKLM\System\CurrentControlSet\Control\Session Manager\Environment\MySystemEnvironmentVariable
Use with care...
