The OLE DB provider "Microsoft.ACE.OLEDB.12.0" has not been registered.

I was trying to run this query

SELECt * FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0','Excel 12.0;Database=C:\Users\File.xlsx', 'SELECT * FROM [Sheet1$]');

I got this Error:
Msg 7403, Level 16, State 1, Line 1
The OLE DB provider "Microsoft.ACE.OLEDB.12.0" has not been registered.

Computer OS: win7 64 bit, excel:32bit
