When you attempt to use the Import feature built into Microsoft SQL Management Studio and you attempt to import an XLSX file, the system let's you point to it and select it, but then throws a "microsoft.ace.oledb.12.0" error.  When this occurs, you need to download and install this:

The issue is that the server/PC needs the ability to open Excel 2007 or higher files and files are required from Microsoft to support this.  Here is a reference link to the article that details it in a forum:
