I am a novice!! Working on Windows Vista Home Premium 2007/Service Pack 2/32bit. Can no longer upgrade any program (i.e. adobe flash, itunes, windows etc..) The programs will look like they are upgrading then at the last few minutes it will say it can't complete the task. Missing %appdata% file. I looked throughout computer saw that it is in my documents folder. What location should it really be in and how do I fix it? Thanks!
