is there any solution to this issue ?
I just installed the topaz & fusion express packages , configured in lightroom 6 ( was already there, but checkd).
When i try to edit in Fusionexpress LR creates the tiff but then nothing happens.
I figured out, that the access rights of the "Topaz Fusion Express 2.app" are different to the other plugi-apps:
drwxr-xr-x 3 admin staff 102 3 Dez 13:34 Topaz DeJPEG 4.app
drwx---r-x 3 admin staff 102 3 Dez 13:34 Topaz Fusion Express 2.app
Nevertheless , changing the accessrights with "chmod a+rx" doesn't fixes it.
when starting the app from within finder, it says: can't open because it's probably damaged...
I have Sierra 10.12.6 running.
Other Topaz apps ( Adjust 5) work fine.
