I was installing the new version of the itunes when my computer froze, so i shut it off and when i turned it on ,the itunes was gone from the computer. when i went to the site to reinstall it it wnt let me. when i look into instal programs it is there but i can not open bc it tells me it is not ther3I want to know how to recover the older version so that i can update it. I can not open or update> If i try to uninstall it tells me that it is not there

Did you try system restore ?If not try it and choose the restore point for a few days earlier before the date when the problem happened to you ?hope it will help you .Good luck
