I have tried to find an open session of PowerDirector and can find none. When I look for open apps in the Task Manager of Windows 10, no sessions of PowerDirector are listed, either as apps or as Background Processes. I did find PDR13.exe listed in the Details tab of Task Manager, but it was listed in the "suspended" status and any attempt to stop the process results in a message that "access is denied".
I have waited hours and retried the application with the same result. I have attempted to re-install the application and I get the "Concurrent user..." message once the instal begins. Is there a lock file or some other process that prevents concurrent uses of the application that I can modify to allow me to open the app? Don't know where to go from here other than delete the application and then attempt to re-install, but if the app is going to close unexpectedly and lock up like this, I am not sure that it is something I want to re-install. Anyone with any ideas?.
