d2d1.dll not working

Hi, I have been having some troubles starting programs because of an error with d2d1.dll. The programs crash on startup with the error 'd2d1.dll is either not designed to run on Windows or it contains an error'. I have tried SFC /scannow and it says there are corrupt files that need repairing but it fails to do so. I looked at the logs and it seems to be d2d1.dll as well as memory diagnostics tool. I have also tried replacing the file but it won't let me in system 32 as its being used by other programs or processors. How do I resolve this as it's affecting multiple applications. Thanks.
