You may get the error "Unable to load CorelDrw.dll. Error Code : 998" when you are trying to launch the Corel Draw.
This problem appears when you have installed "searchqu" application on your system. You may not have intentionally installed this application, it may be part of some freeware getting installed.
Go to Add/Remove programs in the control panel. In Add/Remove program list find the "searchqu" application and uninstall it. Try launching the Corel Draw now. This should resolve the problem.
Update: If you don't have "searchqu" installed, check if you have "iliveid" installed, it also does the same. If iliveid is installed uninstall it.
