Thank you for your answers.
Daomey, I don't really understand what you mean by "instance", is it the ryzom folder and the whole set of files? Only the application and configuration files?
I think Daomei means several separate copies of the game client on harddisk.
Anyway, if you change folder names, uninstallator will be unable to correctly uninstall the application.
If you have space and know where the game is installed and storing your settings, try:
- backup everything game related somewhere
- uninstall the game
- remove all remaining game files and folders
- install or download&unpack a 3.x client
- run it and update
- copy (only) files with your settings back from backup into new installation (need some patience to select just what you need)
I am sorry, I am not sure I can help you more detailed, I have no Windows client, so better ask others who use it in case you don't know where to look for files I talk about.
