The package is called "Visual Basic 6 Working Model", and is the VB 6 IDE + language but without a compiler. I couldn't find it on the Microsoft site, but I got a copy of it with a book I bought. Perhaps that's the only way to get it?
Still, paying €15 for a book is bettern than paying hundreds for the sharp version of VB 6 -- if all you want to do is learn the language.

They SAID that given enough time a million monkeys with typewriters could recreate the collected works of William Shakespeare... Internet sure proved them wrong.
