我是使用windows 7
官方網頁中的解法是到itunes的downloads裡把.tmp資料夾移除再重新下載
If you encounter this issue while while downloading something from the iTunes Store:
Delete your iTunes Downloads folder, located in:
Mac OS X: ~/Music/iTunes/iTunes Media/Downloads Note: "iTunes Media" may appear as "iTunes Music. Also, the tilde (~) refers to your Home directory.
Windows Vista: \Users\username\Music\iTunes\iTunes Media\Downloads\
Windows 7: \Users\username\My Music\iTunes\iTunes Media\Downloads\
Windows XP: \Documents and Settings\username\My Documents\My Music\iTunes\iTunes Media\Downloads\
After locating your iTunes Downloads folder:
Quit iTunes.
Delete the Downloads folder on your computer.
Open iTunes.
Choose Store > Check for Available Downloads.
Enter your account name and password.
但是，我downloads資料夾裡根本就沒有這些檔案可以刪
不是每次都遇到 可能幾星期才遇到1-2檔案
iTunes也很堅持的每次下載其他軟體或更新時就要重下載這些有問題的app
就算已經從iDevices裡下載並更新到電腦中了
然後沒有特定情況下 有時這些死掉的下載又會自動好
還有沒有其他解決方法？
