Hi,

I would like to install graphviz to make TracMasterTickets plugin
dependency graphs available.
I installed graphviz-2.18.exe from graphviz.org on a Windows 2003
server. When trying to visualize these dependency graphs... nothing's
displayed. Activating TRAC LOGGING, I get the foloowing which seems to
be (as far as I understand) that the child process (the graphviz
program) can't be found and then can't be launched. However, graphviz
is in my path (tested from command line) so... any help vwould be
higly appreciated!

thanks,

Pierre
