Do I have to uninstall existing software to use DualDesk?
No, DualDesk can run on the same machine as an existing installation of other remote control software and can even be used to remote deploy, configure and install other remote-control software and setup and remotely configure hardware and software firewalls and NAT routers that would normally require on-site installation of other products. It peacefully co-exists and can be run at the same time as other desktop sharing software including PC Anywhere, GoToMyPc, GotoAssist, WebEx, NetOp, RemotelyAnywhere, Microsoft Terminal Services, Desktop Sharing, RAdmin, TridiaVNC, UltraVNC, TightVNC, RealVNC etc. as long as they use different ports.
