Use the Microsoft ACE OLEDB 12.0 provider instead.

for solving 64-bit related issues.

Good luck!

i write many connection string to connect on XSL file(.xls exetension) but all failed for example:

String sConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + strPath + ";Extended Properties=\"Excel 8.0 ;HDR=NO\"";

But in contrast i can connect to XLSX file with this conection :

 String sConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + strPath + ";Extended Properties=\"Excel 12.0 Xml;\"";

the Error: Could not find installable ISAM.

i remember you that my system is 64 bits(Windows 7) and i have Office 2007 installed

Not very intuitive but I believe this one should work

Source=c:\path\file.xls;Extended Properties="Excel 12.0;HDR=YES;""
