Problem with Installation

Hi i have this problem when i tru to install my Dolphin ,how can i fix it ,Thank you so much ! 

xsl extension isn't installed. Warning! Dolphin can't work properly without it. 
zip extension isn't installed. Warning! Dolphin can't work properly without it. 
Please go to the 
Dolphin Troubleshooter 
and solve the problem.

I would suspect your Hosting Plan is not going to work. Are trying to use a GoDaddy Shared Hosting Plan?
