Corel Draw 9

Hi friends,

i have been using corel draw x7. I recently installed coreldraw 9 (a very old version) on my other computer but there are few tools missing in it like it dont have pen tool, polygon tool and smart fill. i want to know how can i have these options in toolbar in coreldraw9. 

Also please tell me why design made in corel draw x7 is very large in size as compared to coreldraw9.

thanks
