It could be either that you chose to install it on the C: drive at the time of installation. Then, when you moved it, it was still looking for the old place. You can solve that by uninstalling and reinstalling and choosing D: drive when given the choice.
Or, it could be that the game requires it be installed onto the C: drive. Some are like that but not too many. There isn't too much you can do about these type, unless you want to get in and write some code. (not recommended)
