.Net Framework unhandled except on startup

[MauttyKoray]

Right so, title explains it, every time I start it up I get an unhandled exception when attempting to start the game (prior to the launch menu).

Details are as follows:

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 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 would verify the game cache at first. If that doesn't help since the error message is from the .net framework just download and install the latest .net framework directly from the microsoft website. That should solve your issue.

[Alienware Gamer]

Is securom activated?

[Coffeephile2]

Reinstall all versions of .net framework and reinstall Windows Live Marketplace, this is problem with your PC, not game.

[MauttyKoray]

I reinstalled .net framework, that didn't fix the problem

I don't use Windows Live Marketplace, only the GFWL crap the games need, and that is working. I tried out Fable 3 and it runs fine.

Edit: I did try uninstalling all .NET Framework related installs and the GFWL program on my computer, then reinstalled it all and tried again, same issue is still occurring.

[Blacksmith1]

Did you find a fix for this? I am having the exact same issue;
************** Exception Text **************
System.ArgumentOutOfRangeException: Index and length must refer to a location within the string.
Parameter name: length

The rest is the same also.
so far I have verified the game cache, un/re-installed physx, .net framework, GFWL, and deleted and re-downloaded the game itself.
I am still getting this issue. this is the only software on my system not functioning. Everything else seems to work fine.
