Please upgrade your Wine to a recent version first, preferably Wine 1.5.2x
OK, I'm now running wine-1.5.28
you are using an outdated version of 'winetricks' script.
I don't think so, http://winetricks.org/winetricks is still at 20120912
Anyway, when I rerun `winetricks dotnet40` I wind up at the same requirements dialog with the same incorrect " ⃠ Drive C: Required - 64uMB, Available - 64u MB".
Maybe that's not the root problem but surely there's a bug here with the wrong space numbers it displays.
