Question: When I start a new project and want to select the Oracle driver, it suddenly dissapears and I can only select one of the other drivers, what's wrong? ** Solution:** When a driver couldn't be loaded, the driver definition is removed from the drop-down list. In the case of Oracle, load issues are often related to ODP.NET not being installed on the machine, or ODP.NET has been installed but after the ODP.NET installation, the machine hasn't been rebooted yet (this reboot is a requirement for an ODP.NET installation). When LLBLGen Pro can't load a driver assembly, it removes the driver definition from the drop down list.
