d2d1.dll "not correct" // now webcam+microphone don't work

My alienware 18x recently did some updates on the killer wireless drivers.
Now I am receiving a d2d1.dll file is corrupt or not working.
my webcam and microphone have all ceased working at the same time as I began receiving the d2d1.dll error.
Is there any way to get the d2d1.dll file from alienware or dell?
Are there any recommendations on how to fix this please?

Thanks in advance for any help.
