I get this error when I run a scan. NIC vendor does not work as well.
"no mapping for the unicode character exists in the target multi-byte code page netscan"
I run netscan.exe over the network from a shortcut on my desktop.
I still have not found where settings.xml resides - I have not had to: this wonderful app has always worked very well.
This could be a permission issues, since my settings won't update, but it is still reading the settings.xml file because the friendly names that I have assigned still show up.
