--- Comment #14 from Stephen Davies sdavies@sdc.com.au --- Having built wine-1.9.14 from source, my problem is resolved. I suspect that part of the problem came from changes in the FTB directory structure not being properly handled by the upgrade from V7 to V8 as I had to delete everything related to the app and rebuild from scratch using 1.9.14 to get it all to work.
I must say that the wine trace that appears when the app is run from the command line is extremely helpful.
Without that it would have been extremely difficult to work out which 32-bit libraries were expected by the app.
Thanks to all.
