On Mac OSX, was able to successfully install Legacy 6.0 into a Windows 2000 bottle. It was added to bottle with proper icon. Program opens normally. When try to open a family database file however, got a runtime error 445. This occurred several times, both on my own database files as well as the demo file that comes with the program. When click 'ok' the whole program closes.
This is substantially more than I was able to do with the beta2, but still not functional. (BTW, Legacy 5.0 still wouldn't install).
