osu! version: Stable Fallback 20160403.6 (latest)

What GPU do you have?

G31/G33

Yeah, that GPU doesn't support the required OpenGL version to run the latest builds. The only real way you are going to be able to update the game is to upgrade it.

You can still technically get back to the older version you were on before by following one of the two things I'm about to list, however, something to keep in mind is that score submission on maps ranked after October 22nd has already been disabled. The rest of score submission may also be disabled at some point in the future.

Anyway:

1. Open your osu! folder (the default path is "C:\Users\<Username>\AppData\Local\osu!")
2. Edit the file named "osu!.cfg" in notepad (you may need to enable file extensions to make it easier to find)
3. Set the "_ReleaseStream" line equal to "Stable" (e.g. _ReleaseStream = Stable)
4. Save the file and reopen osu!

If that doesn't work, download this installer (direct download link) and run it. If you already have a previous osu! installation with maps, skins, etc, make sure you change the installation path to the correct location on your computer. Otherwise it might install to a different location and you will need to move all of your maps and other data over manually.
