they have different file sizes so i would imagine they are different.
maybe one you used the package installer and it installed to S/L/E.
hwmonitor app usually has to be used with the version of fakesmc it came bundled with.
so either make both the same or remove one. if you look inside the kext you might see the version numbers inside it's info.plist to compare them. remember to rebuild your caches if you add or remove kexts from S/L/E.
