Hi, My dell laptop has not been installing updates or anything for the past year or so - yeah, really annoying!! I need to update my iphone, but since I cannot even update itunes it's a no-go. When I try to update itunes manually (and this error is not just for itunes), it says error creating a temporary file. How do I fix this? And once fixed, will I be able to install updates elsewhere? I have tried deleting and reinstalling itunes the correct way (in the certain order) - it has not worked. Thanks for your help!
