MS Office 2013 Home Student Won't activate

I'm working on a Win 8.1 PC that was originally setup with a copy of Outlook 2013. A license card of MS Office Home Student 2013 was purchased and installed. It installs via a web link. The installation acted liked it worked. However when we go into File, Account in Excel or Word, it says it is part of the enterprise suite and is not activated. So we uninstalled Outlook 2013 downloaded the ISO for Office Home Student 2013 and used the  same Product Key from the Home Student version. Again, it acted like it installed ok, but then it still showed as an unactivated enterprise product under File, Account. In the control panel , it correctly shows Home/Student as the installed version. It seems clear that there is a piece of the original Outlook that is causing the problem. Anyone know how to correct this issue? Last time I ran into this, I nuked and repaved but that is not an option for me this time.

Thanks, experts!!

It would appear that some parts of Office Enterprise remain installed. Look in Programs and Features for any evidence of Office 2013, Business Contact Manager. Lync and all else that is Office and uninstall all of these. Uninstall Office Home as well at this point.

Now restart and try again to install and activate.

Thanks for your prompt reply. In the programs and features it only shows MS Office 2013 Home and Student. No Bus Contact Manage, Lync, Skype, etc. I had deleted all the office related directories as well before the latest reinstall attempt. Probably something in the registry is causing the issue I think. Unfortunately, this PC is in another state hundreds of miles away from me. It was a retail computer and I don't want to risk doing the factory "reset to day one" on it. The programs actually showing up on it are the correct ones for Home Student, but it wants to activate as enterprise.

My Office 2013 is Home (not home/student) and it activates fine. I think Student does not include Outlook (it did not use to) and you had Outlook installed before. So something must be left over.

Uninstall Office again and run System File Checker. Restart and see if that helps.

I would wait before you do a factory reimage to see if suggestions here can fix this for you.
