I must be doing something wrong, but can't figure out what, as I follow the
standard complete installation procedure on a new hp with windows XP.
Installation is always successul (i did it three times), but then as soon as I
try to latex or pdflatex a document in an msdos box, which worked fine under
2.7, I get an error message:
"This is pdfTeX, Version 3.1415926-1.40.10 (mikTeX 2.8)
initexmf: unknown format name/engine: pdflatex/pdfTeX
I can't find the default format file!"
If I try to update all formats, I receive an error message again:
"The miktex configuration utility failed. Do you want to see the transcript? "
And when I do I read:
"miktex-makefmt: Unknown engine: pdfetex
initexmf.EXE: The operation failed for some reason.
initexmf.EXE: Data: C:\Program Files\miktex-2.8\miktex\bin\miktex-makefmt.exe"
So I thought I should change the compiler in the formats tab:
from pdfetex to pdftex,
but then a message comes up:
"Built-in format definitions may not be changed".
I am stuck!
Any hint as to what is going wrong here?
Thanks in advance for any help
As far as I know the directives for generating the formats are in file
formats.ini (at least this is the case in miktex 2.7) in miktex/config. There
can be more than one formats.ini. If your formats.tab shows for one of the
formats as compiler (!) "pdfetex" this probably means that there is somewhere
a broken formats.ini or a formats.ini from another miktex version.
