On Windows XP or later systems, the most common XVT errors are caused by incompatible printer drivers. Such XVT errors can occur even when a report is displayed only to the screen. Sometimes, the errors can be prevented by adding a printer in Windows using an older driver such as the HP LaserJet II and making that printer the default printer.

Because IQ for Windows has been discontinued, a better solution is to replace IQ for Windows with ODBCdL4 and an ODBC based report writer such as Crystal Reports. The ODBCdL4 server and driver provide ODBC access to UniBasic or dL4 data files. Current UniBasic or dL4 licenses include a license for ODBCdL4.
