Microsoft Expression Web 4: ExpressionWeb.exe – System Error

Hi,
I am having issues with Microsoft Expression. Expression 4 web, is not launching how many ever different ways I try to launch it.
I have so many different steps to resolve the issue but in vain. I have already uninstalled the following EW4, .net framework and the encoder package but nothing much changed.
I want to know if something could be done before I wipe out the complete set up.
