Microsoft Office & Creative Project Templates cannot both be insta

[Arlette]

I get the following error message when I try to install above software:
"Setup has detected that Creative Projects Templates is already installed on
this computer. Microsoft Office & Creative Project Templates cannot both be
installed on the same computer. Creative Project templates must be removed
from this computer before installation can continue"
After a bit of research (I am quite unexperienced) I found out it has
something to do with the HP Printer software. The question is : if I remove
Creative Project is the printer still going to work. If I try to remove it :
it obviously says no. Is there any solution for this problem ?
Thanks.
