There are several prerequisite software packages installed with the Iris M software. Some configure the camera, some the video display. In some cases, your virus protection software may identify these prerequisites as potentially harmful and block their installation. You may have actually seen various pop-up warning messages during the initial installation. In order to make sure that the program gets installed as intended, we recommend that you disable all virus protection software during the software installation process. You can re-enable it after the installation has completed and the Iris M software will function normally.
