Error message when trying to create new game

[StuartY231]

I keep on getting an error when I try to start creating. This is what appears:

System.NotSupportedException: No imaging component suitable to complete this operation was found. ---> System.Runtime.InteropServices.COMException: The component cannot be found. (Exception from HRESULT: 0x88982F50)

What does this actually mean? Is there a programme missing from my computer? Please help.
