I just recently figured out how to install wine1.5. My primary purpose is to use Exact Audio Copy without having to reboot back to Windows.
I re-downloaded the installation executable, ran it, and installed it into my external hard drive. When I then tried to get wine to run it, it will give me the initial "Exact Audio Copy is starting up... Please Wait!" but then a second window opens. The second says the following message:
"Unhandled exception -
[X icon] at 0207ADF0 -> ACCESS VIOLATION"
Cancelling the window or hitting "ok" cancels wine entirely.
