We have encountred the same problem, when we tried to install FC on
our machines (under Linux).
We have corrected the FeynCalc.m file (these first few lines
added recently were incorrect-> the use of FileNames etc.).
It works with (instead of first two If commands in FeynCalc.m):
If[!ValueQ[HighEnergyPhysics`FeynCalc`$FeynCalcDirectory],
If[ FileNames["*",
{(HighEnergyPhysics`FeynCalc`$FeynCalcDirectory =
$HomeDirectory <> $PathnameSeparator <>
".Mathematica" <> $PathnameSeparator <>
ToString[$VersionNumber] <> ToString[0] <>
$PathnameSeparator <>
"AddOns" <> $PathnameSeparator <>
"Applications" <> $PathnameSeparator <>
"HighEnergyPhysics")}] == {},
HighEnergyPhysics`FeynCalc`$FeynCalcDirectory =
$TopDirectory <> $PathnameSeparator <>
"AddOns" <> $PathnameSeparator <>
"Applications" <> $PathnameSeparator <>
"HighEnergyPhysics"
]
];
If[FileNames["*",{HighEnergyPhysics`FeynCalc`$FeynCalcDirectory}] ==
{},
Print["Could not find FeynCalc installation.
Quitting the Mathematica kernel."];
];
(for Math versions 3.0 and 4.0 )
