Hi
You don't need to install Access runtime 2016 and don't need to uninstall Office 2016.
We can import data from Excel 2016 into SQL Server by using Microsoft.ACE.OLEDB.12.0, you can use the following steps to import data.
You can download Microsoft.ACE.OLEDB.12.0 from https://www.microsoft.com/en-us/download/details.aspx?id=13255
and install it on your machine.
Then use the connection string provided in the article to read excel.
If you still want to use Microsoft.ACE.OLEDB.16.0 use the below connection string.
"Provider=Microsoft.ACE.OLEDB.16.0;Data Source=C:\Book1.xlsx;Extended Properties=****";
For more details refer below link.
