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
