We need to know which is the problem: if it's what you suggested
(start is not strictly a binary and `find-executable' cannot find it)
then we can just remove start from the list of executable to be
checked.

Admittedly, I don't use Windows and I wasn't able to test the change
on that system, but I made a research and I understood that "start"
was a system program or something like that.  Again, if it's not an
executable, remove the third element of the "start" item in
`TeX-view-program-list-builtin' and we'll need to fix it also
upstream.

Bye,
Mosè
