The game installer throws an error or does not work when I use it!

If game installer throws errors when attempting to install, you can try few things:

  • Clean your PC - Scan with anti-virus software, clean the registry. A good program for general clean up is CCleaner. Scan both your computer files and your registry. The installer can fail if there are registry entries from a previous copy of osu! still present on your system.
  • You can try reinstalling .NET 3.5 Framework. You can find it here.
