It sounds as if the front end has lost its way regarding the location of
$TopDirectory. The front end has its own setting for this variable
outside of what the kernel uses. You can display it by pasting the
following expression into a notebook.
Cell[
TextData[
{"The value of front end $TopDirectory is ",
ValueBox["$TopDirectory"]}
],
"Text"
]
Click "Yes" on the resulting dialog box to force the front end to
interpret the expression.
The ValueBox[] will resolve to a FrontEnd`FileName object that should look
something like:
FrontEnd`FileName[{<drive letter>, <path element1>, ...},
CharacterEncoding -> "WindowsANSI"]
If the <drive letter> is "C:" instead of "D:", you may want to do a
complete uninstall and reinstall of the software. If this is an
inopportune thing to do because of projects that you may be working on, a
stopgap solution is to use SetOptions[] to tell the front end where to
look for the help files. Here is an example of you might do this.
SetOptions[$FrontEnd,
SystemHelpPath -> {
FrontEnd`FileName[{"D:", "Program Files", "Wolfram Research",
"Mathematica", "3.0"}, CharacterEncoding -> "WindowsANSI"]}]
Copying, pasting, and evaluating this expresssion is much easier than
plodding around the Option Inspector dialog.
