On a Windows 7 machine, using Playon Desktop, I find I need to be an administrative user to record.
(I have not yet tried simply running Playon as an administrative user.)
I tried everything else I could think of. E.g., Disabled all the VMWare services, and the virtual network adapters VMWare creates. (which were still disabled while I am recording now. I will go back to trying to make it normal later, or to running Playon in a virtual machine, ) Set the Network type to be Home (Very insecure - you should always use even your home connection as a Public network, if you care at all about security.) Even tried disabling Winddows security essentials and Windows Firewall, though that isn't true now. Rebooted. Tried something from Playon picks. Everything I could find in the online documentation. None of these things were sufficient.
So if all else fails, try this.
