deadfolk: Thanks for the reply - already posted log
in this post Szulak: Remove completely the GOG Downloader, install it again and try to download any game. As soon as an error appear, go to your log file and copy its contents here (or upload it to paste-bin like-service). Please copy the whole contents of log file.
Update: It works in Internet Explorer - but not in Chrome, which I normally use. I am going to try resetting/reinstalling Chrome at a convenient time.
Okay - I did all that. The first time I launched the downloader after reinstalling, I got the error and the downloader terminated. At this time, no log file or c:\Users\...\AppData\Local\GOG.com was created. I launched it again, this time with no error, and the log file was created. I checked the download location and saved settings.
I clicked to download System Shock 2, and the error occured, but the downloader did not terminate. It also did not list the game.
