Could not find installable ISAM

Question

I have the following code :

string excelConnectionString = @\"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\\db\\suc.xls; Extended Properties=\"\"Excel 1         


        

Answer 1

I was getting this issue trying to opening an xls file with a more recent provider. I fixed this issue by changing my extended properties from

Extended Properties="Excel 11.0;"

to

Extended Properties="Excel 8.0;"

I guess Excel 11 expects an xlsx style file.
