homepage Forums Air Combat & Civil Aviation IL-2: FB, AEP, PF Newcomer's Guide: Updating 1946 DVD

Don't know if I am in the right place,forgive if not,but after many years of enjoying IL2,have decided to try and get "mods" to enhance.
Needing a clean install,I thought loading from my original cd would be easiest but seems all I am faced with is "do you want to delete current etc".
Is there a way around this please?
Thank you?
OH,yes,advice on easiest mods [to load] would be most welcome.
