First if the EngravePro menu is in fact in CorelDRAW but is greyed out or unresponsive if you click any of the menu items then more than likely Visual Basic for Applications (VBA) is not installed. To see if VBA is installed you can click the tools menu, click Options, then find VBA under the workspace heading along the left hand side of the dialog box. If you are unable to locate the VBA heading or it is greyed out or it tells you it is not installed then it is not installed and you must rerun the CorelDRAW installation. Note that CorelDRAW no longer ships VBA with OEM or academic versions of CorelDRAW. If you have one of these versions you will be required to upgrade to a full retail version in order to utilize EngravePro from within CorelDRAW.
In some cases (for unknown reasons) EngravePro is unable to properly install itself in the menu bar in CorelDRAW. Re-run the installation to remove EngravePro and restore your workspace. Re-install EngravePro but when asked if you want to overwrite your workspace click "No". After installation completes follow the "Manual Installation" instructions above.
