Best solution would be for you to register with them on at Digital Ally Support Documentation & Other Resources. You can download the manager tool right from their website. I have a disc if that does not work. Few steps is all it takes with registering. They are now using Video Manager II which fixed a lot of issues. We use the DVm-500 and DVM 500P. Having used both, Video Manager II works much better. Just message me if you cant download it. I do believe the disc I have is just Video Manager 1. They emailed me Video Manager II.
