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.
We have one DVM 500+ and one DVM 800HD. The 800HD is garbage. The VuVault Software is the most user un-friendly I've dealt with yet. The old Video Manager Software was easier to navigate through and was on a CD. The VuVault Software doesn't come on a CD and is remotely loaded on you desktop or mdt/laptop remotely.
My department might still have the Video Manager Software CD in a file cabinet. It's the original one, not the Video Manager II
