Does this directory exist?

C:\Documents and Settings\pparisi\Application Data\PLSQL Developer\Preferences\pparisi

Yup

That directory exist.
It contains "default configuration settings file" and "user.prefs" file

Thanks,

Is the directory writable, and are these files writable?

All are read only directories only
can I change those to writable?

Thanks,
