Solution: This error could be caused by several factors (Windows related). Before using Active-HDL we need to register this control. Please reboot your computer and then Start -> Run type in "cmd" and Enter. In the command line type the following line: regsvr32 c:\Program Files\Aldec\Active-HDL 8.2\BIN\popup.ocx and hit Enter.
