I tried to install TeXLive2004 ;
latex runs well but when I try to run texexec 
I have the following error message :
===============================
irun : no perl.exe script
of name texexec.pl can be found.
Aborting
irun : CreateProcess 3
===============================
I have an environment variable 
PERL5LIB=C:\MesPGM\TeXLive\xemtex\perl\lib;C:\MesPGM\TeXLive\xemtex\perl\site\lib
What is wrong ?
Thanks
