What are you trying to install?
I am installing an update to an ERP application. The application had already been installed and running on this server – both the Client and the Server versions. In updating, the installation is successful but when I open/access the program, I get the error message:
OLE IDispatch exception code 0 from Microsoft OLE DB Provider for ODBC Drivers: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified..
