Updating ITunes and error 42404 with Vista

I was getting error 42404 and tried updating ITunes and it wouldn't update, tried a fix and was told it doesn't work with windows vista, I am unable to sync my IPad or my IPod and lost all my music and pictures I had on them, This all shows up on ITunes but will not transfer to my other devices and I cannot up grade because I have Windows Vista, is there a fix for this or am I SOL?
