install on win2000pro

Hello,

I routinely use Emacs/auctex-10.0 on a W2000 pro machine. I am trying to 
install auctec-11.55 and I meet some (small) problems.

The installation (using MSYS) produced no error message. When loading a 
.tex file, the syntax is color-coded as it should, environments, as 
provided by packages such as revtex or beamer, are available in the 
drop-down menus, fonts can be changed as described, in other words 
auctex works perfectly within emacs.

Trouble  starts when I want to compile: for every file, when I click 
latex, it complains that it cannot find file .tex, even though the file 
(with complete path) appears in the emacs status bar. Surprisingly, 
clicking latex interactive works fine.

Clicking view always brings the answer xdvi <filename>. How can I get 
auctex to take into account by default that I have yap installed ? 
Typing C-cC-c doesn't help, as auctex answers nomatch to 
C:\texmf\miktek\bin\yap.exe (or same with /).

One last point: the statement tek-mik.el is better for Win does not seem 
warranted; it only gives access to tex commands, in my case.

Anyway, thank you very much for developping and maintaining a vey useful 
program. I hope you will be able to find out what I did wrong.

TIA,
