Problem to uninstal Office 2013

I have a tablet with  O365 Office 2016 already on it but appears that I had before a folder in programs files as office 15 which is for Office 2013 and I am having trouble then to download others applications as OneDrive for Business.

I delete from explorer the folder Office 15 since the uninstall did not bring me the option to uninstall Office 2013.

Seems like program remains some where because I steel cannot download the OneDrive for Business.

How can I completely uninstall Office 2013 programs?  I found information to do it for Office 2011 and Office 2016 but not for Office 15/2013.

Any one who can provide me guide please

Thanks
