I have an older VB 6 application running on Oracle 10g that is using the following to connect to Oracle 10g. It is running on Windows 2003 Server.

Provider=MSDAORA.1;
Password=myPassword;
User ID=myUser;
Data Source=myDataSource;
Persist Security Info=True;

We are upgrading to Oracle 11g on a Windows 2008 Server machine. I left the connection string unchanged.

Now when the app tries to connect to Oracle, I get an error that more or less says it can't find the Oracle client or it's compnents.

Can anyone shed some light on my issue?
