Problème avec microsoft.net framework

bonjour ! j'ai un problème avec mon jeux, après avoir dut défragmenter mon disque dur, j'ai dût réinstaller mes jeux. Sauf qu'il m'est impossible de réinstaller nfsw car dés que j'ouvre le launcher pour installer le jeux, ça m'affiche ce message : Unhandled exception has occurred in your application. if you click continue, the application will ignore this error and attempt to continue. if you click quit, the application will close immediately.

et attention les détails :

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

************** 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 section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
< 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.
