So currently I am traveling, and only have access to a windows XP computer. Whenever I try to download OSU! it infinetly installs discord-rpc.dll over and over.
Apparently you can also just create a blank file and name it "discord-rpc.dll" and it'll "work". Though this may have adverse effects to your client. But I haven't seen any reported.
The same thing happens to me, but on Windows Vista, not Windows XP. I have attempted to fix this by following what was stated above, but it doesn't work for me.
