Image 1: DLL file
First time I've installed PowerPivot add-ins on Excel 2013. But the problem is while going to run it it shows a message on Windows 8.1 that, "Unable to load msmdlocal.dll". I'm afraid how to solve it. One thing I got in my mind that, if Restart can solve many problems of PC, then why not reinstalling?
Then I've uninstall it completely and reinstall it after re-starting the PC and it works perfectly. I don't know what was the matter for showing the message. Still trying to know that.
