I suggest adding a .NET framework 64-bit link added to the download page. I'm running Windows XP 64 bit and I had trouble installing with only a 32 bit link. I think this would be a good idea to avoid future problems similar to mine.
I get this if you try to install 32-bit framework off of the game installation.General Pepper wrote:
Does this actually fail to install? osu! uses only 32-bit mode DLLs, so in theory there should be no issue here. If it fails, do you happen to have a screenshot/log of the error you saw?
