Well, after running Blue Iris 4 and BIT for many many months something on my system has changed. I don't know if it is coincidence that the problem happened when I upgraded to Blue Iris 5 recently or if there was a Window 10 update that screwed things up. BIT is not starting up when Windows 10 boots up. I'm getting a UAC pop-up "Disable Do you want to allow this app to make changes to your device?" that I never got before and I haven't changed anything regarding UAC. Since my BI server runs remotely I don't see the UAC pop-up and I guess it times out and as a result BIT is not running in the background. I've also seen the UAC pop-up when connected to the BI server via RDP and try to bring up the BI GUI. I never had to answer the UAC pop-up question before. Lastly, if try to restart the BI server computer I get a pop-up that BI is preventing me from restarting. I don't recall that pop-up before. Anyone have an idea on what I can change on my system to get it to behave like it used to without changing the UAC settings to the lowest setting?
