[Qgis-user] [QGIS-LIST] Contour plugin install under OSGEO4W - follow-up

[M.E.Dodd]

Interesting that someone says contour plugin works via windows standalone as on my xp machine via windows standalone it won't work with this error:
"The process failed to start. Either the invoked program is missing, or you may have insufficient permissions to invoke the program."
