Pine64 install works but I cannot get Designer to open a configuration file

I have installed the Ubuntu image with openHAB using “pine64_openhab_20160915_8GB” . The install works and I can use web access to get the main menu, but I wanted to use Designer on my MacBook Pro to make changes to the configuration.

I set up a Samba server so that I could read the files on the Mac. After some tweaking with the samba/conf file to set it up to the proper locations (The image sets them up in the “opt” directory and not in the “etc” directory like so many other examples) I can open the files on the Mac with a text editor.

But when I try to open them in Designer it says that" the chosen directory is not a valid openHAB configuration directory".

Can anyone tell me what I am doing wrong and point me in the right direction?

The opt/openhab/ directory has the following sub-directories:
addons
conf
LICENSE.TXT
runtime
start_debug.sh
start.sh
userdata

The Samba server was set up with:

[openHAB-conf]
comment=openHAB site configuration
path=/opt/openhab/conf
browseable=Yes
writeable=Yes
only guest=no
public=no
create mask=0777
directory mask=0777

[openHAB-userdata]
comment=openHAB userdata
path=/opt/openhab/userdata
browseable=Yes
writeable=Yes
only guest=no
public=no
create mask=0777
directory mask=0777

The directories that I found have the following subdirectories

opt/openhab/conf

html/
icons/
items/
persistence/
rules/
scripts/
services/
sitemaps/
things/
transform/

opt/openhab/userdata
cache/
deploy/
etc/
generated-bundles/
hueemulation /
kar/
lock
logs/
mapdb/
persistence/
port
tmp/

openHAB Designer does not appear to like that structure.

Thanks for any assistance you can provide.

Are you using Eclipse Smarthome Designer or the old openHAB Designer? The old Designer is not compatible with openHAB 2.

Thanks, I was trying the old designer…I tried the Eclipse for Mac and it gives me an error when it starts up. So I was trying to use the old designer

The error is
"java.lang.RuntimeException: Application “org.eclipse.smarthome.designer.ui.application” could not be found in the registry."

Know of any way to correct this?

Thanks for your response.
