Hi I found this thread online which is exactly the same issue I am having. Has this problem been resolved?
"I installed SQL Server 2012 SP1 Data Mining add-in for Excel 2013 64 bit on Windows 8.1 64 bit Enterprise. I then ran "Getting Started" to complete the add-in setup and connect to the SSAS DB. After I opened the "Sample
Excel Data" file to test I noticed the "Table Analysis" tab under "TABLE TOOLS" appeared on the ribbon blank (without the text "ANALYZE" on the tab). When I clicked on that tab I was able to see the "Table Analysis Tools"
buttons but I keep getting the "Object reference not set to an instance of an object" error message when I try to run any one of them and exiting out of Excel disables the data mining add-in. Is this a known issue and if yes is there a
hotfix available? Thank you."
I've also download the follwing hotfix which hasn't helped
