Oracore11.dll not found -- ADODB Open Connection

user595684Feb 25 2008 — edited Nov 10 2009

I just posted this in "Oracle Develepor Tools for Visual Studio" but I think it belonged here....

A user of our application just switched from 10g to 11g. Only Instant Client 11g is configured on the user's PC. Now the Open call in ADODB interface (for connecting to DB) in our app fails with the message "This application has failed to start because oracore11.dll was not found. Re-installing the application may fix the problem." This occurs using either a Provider of OraOLEDB.Oracle or msdaora.1 in the connection string in the Open call. Do I need to have the user download and install an 11g ODAC or MDAC component or do I have to do that and rebuild the app? I see there is 11g ODAC but Microsoft doesn't seem to have an MDAC update. Or is there some other solution?

Thanks,
Chris
