I have used Ultra VNC Single click for supporting customers with XP for a number of years. Its great for me as I can get them to download one exe and when they run it, it connects directly to my static IP address(circumventing their firewalls and routers) and I can see there machine, remote control it and transfer files. I include the exe in the build of my software so it always on the machine. The later version that supports Vista and windows 7 is less reliable and crashes a lot.
I now need to find a replacement as my business expands can anybody suggest a similar product that works from customers end to circumvent the firewall and connects direct to my IP needs to work on XP Vista & Win 7?
