Steam - Medieval 2 Total Wars installation

Bonjour à vous,

Ma soeur m'a offert Medieval 2 Total War hier et lorsque je veux l'installer rien ne s'ouvre, alors j'ai fouillé sur le net, apparemment ça serait la cause de Framework. J'ai alors installé tous les Framework (enfin je crois bien) et maintenant je me retrouve avec un message d'erreur visible à cette adresse : https://imageshack.com/ et un rapport d'erreur (au moins j'ai avancé dans le problème car là il y a quelque chose au moins !) Aidez-moi s'il vous plaît !

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 machine (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 machine
rather than being handled by this dialog.
