/usr/share/ati/fglrx-uninstall.sh: 32: cannot create /etc/ati/fglrx-uninstall.log: Directory nonexistent

[Warning] Uninstall : inst_path_default or inst_path_override
 does not exist in /etc/ati.  This suggests that the AMD driver
 is not installed, the AMD driver is only partially installed,
 or the current AMD driver installed is an older version than the
 one this script was designed for.  Both files listed above are
 required for determining where installed files are located.
 To force uninstallation of the driver by guessing where the
 uninstallation files are located, set the force option
 re-run /usr/share/ati/fglrx-uninstall.sh (this is not recommended).
