when i try to upgrade my amigasys3agaplus wb3.1 installation to 3.9 in winuae at 50% and at 100% it says object not found in the installation window. installation progress is too fast in that case anyway and i don't actually see files being copied. after that the os is totally bugged, just a grey window with the white workbench bar on top and the mouse cursor after reset.
to install i mounted the os 3.9 cd as a directory, device cd0 labeled AmigaOS3.9 and could access the cd perfectly through the workbench. the same issue when checked as pc-cd-rom active in winuae options:
amigasys automatically detects the cd and wants to upgrade but it seems to me that it doesn't copy files, even deletes existing system files
what am i doing wrong?
