Question

I am reading the contents of an excel sheet in my application using:

 OleDbConnection con = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";Extended Properties=Excel 8.0");
 _myDataSet = new DataSet();
 OleDbDataAdapter myCommand = new OleDbDataAdapter(" SELECT * FROM [" + "My Sheet" + "$]", con);

myCommand.Fill(_myDataSet);
con.Close();

This is failing in 64 bit systems with the error:

Microsoft.Jet.OLEDB.4.0′ provider is
not registered on the local machine

How to make this work in 64 bit machines?

Answer 1

Microsoft.Jet.OLEDB doesn’t have 64bit version, only 32bit. Compile your application as 32bit (Platform target: x86 in build option).
