Ok, so every time I try to open Osu! I get a window message that says:

Unhandled exception has occurred in a component in your application. If you click Continue, the application will ignore this error and attempt to continue.

Could not load file or assembly 'Accessibility. Version= Culture=neutral. PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging

For example:

<system.windows.forms jitDebugging="true" />

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

No matter how fast I click the error message closes, and reopens as soon as it closes.

If I click "Continue" fast enough Osu! starts, and the music plays, but the Osu! window disappears, and the error message stays there, and won't let me click anything or exit out. (the only way to close Osu! being the Task manager.) Please Help.

If it helps any I run Windows 7 32-bit OS
Bump, please help... I'd really like to be able to play again...
Try finding and uninstalling your .NET framework 2.0 and re-installing it. It is possible that it is corrupt and causing the problem.
This is definitely the case. Downloading the .NET 2.0 framework from http://www.microsoft.com/downloads/deta ... laylang=en and running a repair should fix it.
I uninstalled what you said, but everytime I try to start the setup I get this.


EDIT: Also IDK if Microsoft .NET Framework 4 Client Profile for Windows 7 x86 has anything to do with it.
Uninstall client profile and any other .net installs, then install 2.0. you can reinstall 4.0 afterwards if necessary.
I'm still getting the same message. Is there any other place besides the "Uninstall a program" thing where I'm missing something?
