Rony,
Even if you use one of the methods to increase the path limit on your
system, the NSIS installer still has a limit on the length of a string it
can use.
If you increase your path limit and the path is longer than the NSIS
installer can handle, the installer will refuse to update the path. You
*have* to do it manually in that case.
