RSimpkinuk57: Hi Grandadam,
Is the app called setup_banished_2.5.0.9 ? Where did you put it when downloading? How is your computer configured? With what anti-virus? How did you try launching it and what messages did you get?
I had no particular difficulty running it on my Windows 10 (twice; once on my desktop and again on a laptop). I have only one user id, which of course has full administrator privileges. I'd downloaded with a "Save as" to a folder I use for everything from GoG, and guess I ran it from File Explorer. Between Windows and my anti-virus, I seem to remember being asked two or even three times to confirm yes I really, really did want to let the setup do things to my system.
Many thanks for that help - it seems I can't "launch Banished" (and it is 2.5.0.9) but instead start it by going to Win32 then applications 32 and the game starts up. Bizarre but I am in and it looks good.
Again thanks for your assistance - I did save it into a dedicated Gog.com folder.
