GVEdit is not able to display the class diagrams and shows errors

[AlGantori]

Hello,
I just installed tsviz for the first time, and graphviz download for Windows.

When I open diagram.png in GVEdit I see only "garbage" characters its output consoles shows
working on S:/_W/ARP/UPS.TS/SRC/UPS.TS.RC4/diagram.png
Error: : syntax error in line 1 near '�PNG'

The diagram.png opens in other tools like Adobe FireWorks but only a static horizontal list of diagrams is visible I can't more them around.

I have attached the diagram.png
Let me know what other info I can provide you or email you.
Thank you.

The output is an image, not a graphviz file
