If you are trying to redo it, just make sure to delete the old prefix (either through winetricks --gui or just manually delete the .wine folder from your Home directory).boat wrote:
Well I have already, but I'll try redoing it all. Would reinstalling/installing a different (confirmed working) version of wine also be something to try?
I got the same error just now when I tried running osume.exe, but I didn't do the dotnet20 setup yet. When you try rerunning the command in a clean prefix, make sure it actually finishes (took maybe 2 minutes to complete for me in the past).
I've seen osu! run fine on wine1.6, and I don't believe anyone had any problem with some previous versions, but it's nice to be on the latest one if possible. On raring with just the official ubuntu-wine PPA added for Wine, the latest should be 1.7.2 (you might to reinstall wine using wine1.7, or just select it from a package manager like Synaptic). But in any case, wine1.6 should work fine.
