Can I install AstroWorld 2001 Prime Edition for free?
No, you can't install this application for free since it's on a shareware licence. I've checked the official website, but the Prime Edition doesn't appear to be available. You can check for prices of this application on the link posted below. There is also the possibility to download a DEMO version of the product from the same page.
thank you Stephen for your answer :-) AstroWorld 2001 is the prime edition; You can install the demo version for free but the demo version has restrictions !
