I have the following code :

string excelConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\db\suc.xls; Extended Properties=""Excel 12.0;HDR=YES;""";

// Create Connection to Excel Workbook
using (OleDbConnection connection =
             new OleDbConnection(excelConnectionString))
{
    OleDbCommand command = new OleDbCommand
            ("Select * FROM [Sheet1$]", connection);

    connection.Open();

and i get the following error :

Could not find installable ISAM.

at connection.Open() . Any ideas ?

I had the same error, but none of the suggestions above worked. In my case all I had to do was to change my connection string to this:

string connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + FilePath + ";Extended Properties='Excel 12.0;IMEX=1;'";

Note the Single Quote around the Extended Properties attribute ('Excel 12.0;IMEX=1;'). Once I added those single quotes the error disappeared!
