I don't know if you can do an upgrade from such an older version. I had
VT4.1 and went tto V2007S. It installs in a separate directory, but, you
can
always make a duplicate of your old version as a precaution.

Two issues:
1) Visio 4.1 is too old to qualify for an upgrade price, but you can
"upgrade" to Visio 2007 by unstalling a complete version of Visio 2007 ontop
of Visio 4.1
2) When upgrading, it should detect the older version and and if you want to
preserve the old stencils.
Though you may be able to use the old stencils, some of the add-in programs
may not work.
