This has been going on here for several releases, but I haven't seen anyone else report it, so I am pretty sure it is on my machine.
During installation of a new release, I don't get any error, but the installation hangs at the same point each time. The attached screen show shows what it is showing when it hangs.
"Extracting files... C:\Program Files\xLights\xScheduleWeb\inc\sidebarPlayerStatus.html"
To get around this, I first go into Task Manager and cancel the installation. I then go into Apps and Features and delete "xLights version 2018.xx" (what ever the previous version was.) After this, I simply load the new version and everything installs and works.
This is definately not a priority as I have a working method to get things back up and running. I just wanted to see if I'm the only one, or if others have run into this.
