Was it working before and stopped? Or did it nor work the first time you used it?
That file is supposed to be installed by any piece fo software that needs it. If it didn;t install the file then that's sort of a bug in the program. If the file WAS there (program was working) and is now missing, that's something else entirely...
The file can be hand installed with some evffort, or you can try re-installing the sofwtyare that needs it if it was working before.
