Actually, your Windows Environment settings have to
set. It is within Control Panel. But I do not
rememeber
the actual postion.
Moreover, you tell me the Windows Version that you are

using.
Your setting through Start Menu -> Run is not going to
change the default settings of Environment Variable of
Windows.
Either you have to use command prompt or set the
Environment Variable through Control Panel.
Use Textpad or Visual Cafe program which will enable
you to overcome the problem.
