Tried upgrade to 1903, but was prevented.
I've always had problems when doing upgrades, so I've avoided them and stuck with version 1709, but decided to finally try out 1903 last night. I had downloaded the .iso file and gotten instructions from members here about exactly how to do the upgrade with it. So I clicked the .iso, was asked what program I wanted to open it in, and I selected one called something like ".iso viewer", and then clicked "setup", and immediately got an error message saying the "autorun" file is corrupt and cannot continue. I tried 3 times with the same result.
What am I supposed to do now? I'm tempted to just stick with 1709 for another 6 months.
