This problem occurs once you update your windows as you can see I am using windows 10(64bit) version 1903. Just follow this steps below:
1st. check if WMVCORE.DLL if it is already available in your computer you may check the file at C:\Windows\System32
2nd. If the files is not missing maybe your WMVCORE.DLL is corrupted or try to download this files below and paste it. (Don`t forget to backup WMVCORE.DLL)
