Slicer in Excel 2010 Inactive and How to install PowerPivot?

[Hashiru]

Hello every one. I have just installed Excel 2010, but the slicer button is inactive. How can I get it active?

Also my computer has a windows 7 with 64 bit. I want to install PowerPivot. Which option shall I select from the available options.

Thanks

Can you provide more information?

Were you in a PivotTable in an xlsx ( i.e. a non-Compatibility Mode type ) workbook?

What options are you referring to for the PowerPivot instal process?

If your version of Office is 32bit, install 32bit PP.
