I have installed SQL Developer Data Modeler 220.127.116.110. It seems to be working, but when I start it up, I get the following message: **** WARNING -- Unable to find central directory for C:\Oracle\product\tnsnames.ora
The tnsnames.ora does exist in that directory and I cannot find any reference to "central directory" in the documentation. I don't want to ignore warnings if possible, but I'm not sure what to do with this one. Suggestions?
