can I download 2004 proseries

No, unless you have access to a fairly reliable time machine.

Did you ever purchase the 2004 program?   If yes, then possibly you can download.  Login into your account    https://accounts.intuit.com/     

Once you get to the ProConnect screen look for the dropdown Previous Years    

My account shows back to 2006 which is first year I purchased

And I could possibly win the Boston Marathon, but I'm not betting a lot of money on that happening.

Lacerte goes back to 2002. I don't know if you can get there from here.

can I done income tax year 2003 2004?

If you (a) Install Lacerte Tool Hub and and (b) follow the instructions in the link, then YES to DOWNLOAD LACERTE.

That is not true for ProSeries - There you gotta know somebody that knows somebody who has it.
