Hi Raymond,
Please install your ROOT in c:\root.
It is very likely the long name with the space in it (i.e. Program Files)
which gives you the error.
Another way out is to specify the path in ROOTSYS for the long names
betwee a pair of "; however, I would advise you to use c:\root as the
ROOTSYS.
Cheers,
Nick.
