Issues getting iModel ODBC driver to work in Excel

Hello...I'm new to this ODBC thing and I have been having issues even getting it to work.  I was trying to use the 32 bit version since I had Office 32 bit but that failed, so I ultimately got IT to install the 64 bit version so I can use the newer 1.6 ODBC driver. I followed the instructions that came with it, but I am getting errors trying to access the iModel tables.

The first time I tried the Get Data>>From Other Sources>>From ODBC, but when I select the iModel 1.6 data source, I get this error...

Weird point, the 'one time' screen upon installation of the driver says imodel2.0, not 1.6 so not sure if that is something. And I also mistakenly chose the second option before going back to select the first option.

So I tried the Legacy Data Connection Wizard method, and I got a new screen that isn't in the instructions...

Using any of the methods, I get the error message 'Unable to connect to data source. reason Access denied.......'

The data source is in my 'My Documents' on my machine. And I've tried different location on the server too. But Bentley support insists it is a permissions issue (and then told me to come to this page for further assistance). I don't know how to progress from here. Is it my installation?  Is it the iModel I'm trying to read (I've tried several_?  I don;t know. Any ideas would be greatly appreciated.

Cheers,

Austin.
