I tried to use one of the graphviz functions to visualize a graph, butRaw Message

did not succeed. I tried the attempt of Michel Talon but got an error

message:

I then added the path of the dot.exe in the file_search_maxima path

list, which did not help:

append(file_search_maxima,["C:/Programme(x86)/Graphviz2.38/bin{exe}"]);
