I currently have a spreadsheet that's looking up data in another spreadsheet using ODBC

When trying to retrieve the latest data, i am receiving the below message:

Could not find installable ISAM

I have tried to re-register the Msexcl40.dll and ensured that the registry reflects the same file path for this file (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Excel), however this has not assisted in the solution.

Does anyone have any ideas

Many thanks

Matthew
