Ok, I reverted back an update so I could test. When I turned off my antivirus dugi launcher updated fine and started ok.
It also worked once I restarted computer and antivirus was back on.
I will not be sure if it was the antivirus causing the problem until the next dugi update occurs and I can test it again.
If it is the antivirus then I dont know what the problem is as I had no problems with them both before and dugi is allowed through the antivirus.
