If you install FeynCalc using the automatic script, but not to the default location using the InstallFeynCalcTo option of InstallFeynCalc, and you already have a version installed in the default location, then the previous version gets loaded rather than whatever you just installed.
I came across this just now testing the development version, and was confused why the stable version got loaded, but I would guess it will also error in some way if you didn't already have FeynCalc installed.
I would assume the issue is this line at the end of the install script:
which should probably be something like:
Get[packageDir <> "FeynCalc.m"]
