I have installed feyncalc 9.3 and feynhelpers (automatic installation), but I found the FeynArts 3.11 can not work.
In my pc, copying FeynArts into {$UserBaseDirectory, "Applications", "FeynCalc", "AddOns"} or {$UserBaseDirectory, "Applications", "FeynCalc"} is not work.
This code "$LoadAddons={"FeynArtsLoader"};" can not work.
