Hi,
The '.emtl' files do exist in both (I've done a search for them),
they are created under the ....\configuration\org.eclipse.osgi\bundles
folder in the installation.
It is the same version of acceleo, I installed it using the update manager.
the org.eclipse.osgi is a different version in Papyrus and TopCased,
it is code from this module that is used to find the .emtl files,
thus I figure it may be this that is causing the issue...but perhaps not!
(I have copied this email to the forum as you request.)

Hi David,
Thanks for carrying this thread here :). Unfortunately ... I fail to see
why you get a failure in one case and not the other. Could you check
your configuration to see if there isn't more than one version of
Acceleo installed in the case of TopCased? This is in Help => About
Eclipse => Installation Details => "Plug-ins" tab and search for the
plugin named "org.eclipse.acceleo.compatibility" there. You should only
have a single one. If you have only one ... I have no idea as to why we
wouldn't be able to retrieve the emtl files in your TopCased use case.
