Replay Music tried to install a driver called jaksta_vs.sys. That driver causes conflicts with Windows “Memory Integrity” so install failed. I uninstalled Replay Music but jacksta_sys remains on my system. I can’t delete its registry entries. The jaksta.com website has NO way to contact them, the only thing in all their online help related to removing the driver is a statement that “You can uninstall previous versions via the Windows Control Panel.” Ok, there are a lot of options there. Which one? Device manager doesn’t say anything about it. All the ways to see installed programs and services don’t show it. I don’t know what it’s doing to my system, I don’t want it. Replay Music site simply says I need to disable Memory Integrity. Not doing that, why wasn’t I told about all this during installation? Both sites have made me a permanent non-customer.
