[CR #582762] If Sybase IQ 15.1 and ETL 4.9 are installed on the same machine, and you uninstall ETL, you cannot then use Sybase Central™ to connect the IQ demo database.
Workaround: Either:
Copy the dbodbc11.dll under c:\IQ\IQ-15_1\bin32 to c:\IQ\ETLDevelop49 after uninstalling ETL, or,
Create an ODBC data source using the Sybase IQ driver, and select “ODBC data source name” from the Identification tab. Enter the data source name created when connecting Sybase Central to the IQ demo database.
