I think I may finally have gotten rid of all the warning windows about needing MS Outlook. Go to the NOD32 Control Center, select NOD32, and run NOD32. Set up the target tab, then go to the setup tab and uncheck Use MAPI Interface. Next, go to the profiles tab and click on Profile. Choose Default profile and Save. Next, go back to the target tab and deselect your hard disk etc. so no target is chosen. Check the setup to make sure MAPI is still deselected. Then go to the profiles tab and save this profile with a new name, such as CommandLine. Finally, in the programs that call up NOD32, add the parameter /config=CommandLine. Otherwise NOD32 when called up will revert to its own commandline parameters which include MAPI and result in the warning window.
