I had to reformat my windows (windows 7 64bit) a few days ago, but since then MWO does not launch in 64bit mode.
I get the following error message.

I have tried running the repair tool but just says it cannot find any problems.
Any help please?
Thanks!
EDIT: As far as I can tell windows is up to date.
