Microsoft .NET Framework Error

Hello,
I have a big problem.
I have searched the internet for solution and try to make it self.
But i cant make it.
I had this error from Microsoft .Net Framework box.

Unhadled exception has occured in a component in your application.
If you click Continue, the application will ignore this error and attempt to
contininue,

Could not load file or assembly 'Accessiblity, version=2.0.0.0,
Culture=neutral, PublicKey Token=b03f5f7f11d50a3a' or one of its
dependencies. The system cannot find the file specified.

This was the message that i must type from the error box.
And there is a Detail button that i can copy paste -.- .

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
enabled.

For example:

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

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.

I hope you can help me, because i have this with some programs.
Almost the same error.

My PC runs Windows 7 64bit Home Premium.

I only can find .Net framework 4
Do you can say where i can find the unistall of .Net framework 4 to 1

I deleted .net 4 and restart my pc.
Then i downloaded .net 1 with no problems.
But with .net 2 it say that i have installed it already.
Then i found .net 2 sp2. it says that i need to fo to "Turn windows feutures on or off"
