Hello

I do not think that this is a right place for such questions. In USENET
you can get much more assistance.

If you are running Windows you should use MiKTeX (www.miktex.org). It
offers very good easy-to-use installer.
If you are running UNIX, probably you already have it installed. Type
latex at command line and see what happens.
On the same web site you will find also a lot of TeX-related information



With best regards,
