you can get all of information to start working with "ENVI-met" and to continue it, at the formal site of software. (http://envi-met.info/hg2e/doku.php)
ENVI-met manual has to be read. And join ENVI-met blog. If you didn'succeed after all, a one to one session or course has to be taken. Sorry for being late to respond. All the best wishes. Mohammad.
