Really? I wasn't aware of that. Though I just did it and it failed anyway, but I noticed that even after reinstall Wine!, Osu was still in some fashion installed(the version number was 0.0.0.0, which is nothing new but I can't seem to figure out how to uninstall it, since it also crashes when I try to remove it via wine). Is there any way to clear out wine's registration of Osu somehow, so that it can start the install fresh?
--EDIT: I feel a bit closer to success. After reinstalling wine clean and removing osu entirely, I reinstalled it and it still failed when trying to publish it's product information. Now, however, after changing the windows version to 7/Vista, I get this specific error instead of the generic crash:
Application has generated an exception that could not be handled.
Process ID=0x29(41), Thread ID=0x2(42).
If I click cancel to try to debug it, I get:
No registered JIT debugger was specified.
EDIT EDIT:
http://pastebin.com/n9ZVwRwx it ocurred to me to try to run the installer through the terminal so I could get the error logs of whatever's wrong. It's pretty much gibberish to me but somebody might be able to make heads or tails out of it?
