Start by looking at Tools | Add-Ins to see if Analysis ToolPak is listed. If
it is, check the box. If Analysis ToolPak is not listed, use your Office CD
to install it. Otherwise, explain what you mean by "could not be restored."

I am a student.
My original office 2003 professional edition did instal " data analysis ";
I had installed " data analysis plus " from Keller's statistics textbook"
thereafter;
" Data analysis " then disappeared, and only " data analysis plus "
remained.
I had been told by my tutor that it could not be happened and was told to
reinstal
from original Office CD to recover the " data analysis " from original
excel.
I did it, but " data analysis " could not be restored, but with " data
analysis plus" left only.
What can I do now?
