excel - Error: "Could Not Find Installable ISAM"

Question

I've written some VBA code in an Excel workbook to retrieve data from an Access database in the same directory on a desktop. It works fine on my machine and several other machines running Windows XP, but when we tested this on a Vista machine, we encountered the following error:

Could not find installable ISAM

I've done a bunch of searching online but can't seem to find a concrete answer. The connection string seems to be fine, and, as I mentioned, it works on several machines.

Does anyone have any idea what could be causing this? My connection string is as follows:

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:ptdbProgram Tracking Database.mdb;

Thanks

Answer 1

Place single quotes around the Extended Properties:

OleDbConnection oconn = 
    new OleDbConnection(
        @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties='Excel 8.0;HDR=YES;IMEX=1;';");

Try it, it really works.
