Power Pivot was installed, but is not appearing as a tab

Hi All

I'm at a client site and I downloaded the _x86 version of Power Pivot, and it is not appearing as a tab. Any help getting this running would be appreciated.

Excel 2010 (with Office Pro), Windows XP SP3.

In the Addins dialog it appears in 'Inactive Application Add-In' Addins
When I go to Manage COM add-ins, it appears unchecked.  When I check the checkbox and hit Ok the dialog closes, but Power Pivot does not appear as a tab.  When I go back to Addins it does not appear as an active add-in. COM Addins

Have you tried this yet? (https://popbi.wordpress.com/2013/01/31/powerpivot-addin-wont-load-you-may-need-visual-studio-2010-tools-for-office-runtime/

I've found a couple different threads with that com error that were solved from this.

Edit: the base of that comes from http://msdn.microsoft.com/en-us/library/ee210599.aspx - which i find easier to read, personally.

Is there anything specific you can point to, preferably with some experience behind it?
I'm not real big on the 'here's a link, now you fish for it' style of solution.

I did run across the Microsoft Visual Studio 2010 Tools for Office Runtime requirement biting me in the rear when I was putting powerpivot on an XP machine a year or so ago w/office 2010.  It resolved it in that case.
