Thanks Gert for your reply. It turned out that I was able to download the Mac OS X drivers from the website. I tried a few things but the app still gives the same error msg before (i.e. the subject line) Gert van den Berg wrote: > > Some modifications to Wine might still be needed to expose the Mac > driver's interface to the Windows application in the way that it > expects it... > OK, I'll ask that question to WIBU support... unless this is a wine development thing?

I would like to avoid virtual machines as much as possible (although I did try out VirtualBox), dual boot is better still but I do that rarely because of the time it takes to reboot. That's why I prefer wine, especially when I just want to do something quickly on a windows program. I want to have a decent crack at getting the app working in wine before I wave the white flag.
