I am a little nervous to install over my "baby" or working install of Orbiter as I have included numerous custom sounds and mp3s. I am considering renaming my sound folder before install to preserve its contents. If I ran into problems and wanted to go back to 3.5, what all would I have to undo?
The installer do not delete "Vessel" folder, nor mp3 nor root "sound" folder. So other addons sound are not impacted at all by install.
If you don't like it you can still reinstall the current 3.5 version (available on my download page). I've put a limitation so it doesn't
install any more on Orbiter 2010 but there is a "install manually" instruction in the installer that will perfectly do the job..
The only things you should NOT do is install a old 3.5 pack and reply "yes" at "remove old install" because this one will delete the
folder "Sound/Vessel" used by some authors.
To be 100% sure simply save the folder "sound" before, you'll have all the addon's sound saved.
----------------
If you are a developer take care all versions uninstall the folder "Sound/OrbiterSound_SDK", this folder should usually NOT be used
to put your C++ source anyway. By saving "Sound" folder before you are still 100% sure nothing will be messed.
