How to Convert LaTeX to dvi, ps, pdf and HTML formats | Mathematical Institute - University of Oxford
Dear friends of MHF...
... recently I had to buy a new computer and many tools perfectly working with the 'old' operating system XP have problems with the 'new' operating system Windows 7. One of these tools is WinEdit... when I try to use one of the compilers to convert a Tex file into a Pdf file it appears an 'error message': impossible to find the file ...
Now I have two questions for You...
a) what the possible reason of that?...
b) do You know some downloadable compilers to convert Tex files into Pdf files?...
Of course: any help will be greatly appreciated!...
Kind regards
