Hello, Data Analysis wasn't available in my Tools menu so I followed the intructions: Tools > Add-Ins... Check the selection for Analysis Toolpack Click OK Nothing happened. Once again,- nothing, no Data Analysis in Tools menu added. Then I found on the Internet that the problem could be a minimal install of my Excel. O.K.next thing I did is reinstalling entire MS Office. The message I get as soon as I open Excel is the Analysis Toolpack is not possible to locate ("introuvable" in french). Idem for Toolpack VBA. I wander how it got "dislocated" and where. Could you, please, provide me with some advise?
