After Windows updates installed on a PC and a reboot, for some reason now the Excel 2010 PowerPivot option is missing from the tab up top.
I looked over these two articles but neither helped resolve. I have reinstalled the PowerPivot software for both 32 bit and 64 bit and rebooted but it's still an issue.
I looked over these two articles and neither seem to help any.
Tried installing both these and then reboot.
This is on a Windows 7 64 bit machine by the way and everything seems fine with everything just like other PCs. Any ideas what else I may try to resolve?
