Well, I have wasted more time without being able to make any progress. I am currently running SkyDemon version 18.104.22.168. quite successfully on a Windows 10 laptop.
On trying to upgrade I get the message SkyDemon requires Microsoft.NET Framework 2.0.
I have tried to search Control Panel and elsewhere on the laptop for Framework, and do not find it on the laptop.
I have just renewed my SkyDemon sub and do hope someone on your team will try to find a solution for me. If you think I should download and install something please advise me very specifically what to download as there seem to be a lot of choices.
Is use of this forum the right way to communicate about this?
