An instance of the service is already running

[Stephen JP]

No doubt this is an old chestnut, but I had NPVR running well on my windows 10 machine. Then it stopped. I uninstalled it and tried reinstalling. Error message during installation: unable to start service...an instance of the service is already running. Re-did this several times, checking that the service did not exist after uninstallation. When I try to run NPVR after installation, there's an error message saying the program has stopped working. Log zip attached. Answer is probably obvious, but I need a pointer. Many thanks

This happens every time on my win 12 installs. Killing nrecord task an starting the service work or just reboot.
