Hi,
It sometime happens that attaching the Analysis ToolPak fails. (at least you can't see it on the Data ribbon.)
Solution: Choose File, Options, Add-ins, Manage: Excel Add-ins, Go,
Uncheck Analysis ToolPak and click OK.
Then repeat the attach process: File, Options, Add-ins, Manage: Excel Add-ins, Go,
Check Analysis ToolPak and click OK.
Go to the Data ribbon and see if the ATP shows up in Analysis group, far right.
