Launcher crashes using SweetFX

[Smilinjack]

Diebels,
MS Update KB2670838 is implemented regardless of IE 10 install. In fact, if you install the IE 10 windows update, KB2670838 also installs.
KB2670838 apparently is a MS DX "fix" that causes the compatibility problem with SweetFX and consequently the launcher crashes in COD.
I had to remove SweetFX from COD to solve the launcher crashes. SweetFX needs to be updated somehow to be compatible with the updated DX.

If you getting launcher crashes with the MS updates installed and SweetFX in the game, either uninstall IE 10 and/or KB2670838 or remove SweetFX from the game. Either action will solve the launcher crashes.

However, a new MS update to the DX installer is on the horizon. That update will require that the fix applied by KB2670838 be installed. So, removing KB2670838 now is a temporary solution.

Hope that helps. If you get SweetFX to run with KB2670838 installed, please let me know.
Regards,
