Apple Application Support 3.1.2

Apple Application Support is part of iTunes, there is no stand-alone package. To install it separately, follow these steps:

1. Download the installation file iTunesSetup.exe (or iTunesSetup64.exe if you are on a 64-bit system) from the download link below
2. Extract it (it's a zip file despite the .exe suffix). Here's how using using 7-Zip:
   1. Right-click the file in Windows Explorer
   2. Choose 7-Zip from the context menu
   3. Choose "Extract to iTunesSetup" (or "Extract to iTunesSetup64")
3. Open the folder iTunesSetup (or iTunesSetup64) created in the previous step
4. Double-click the file AppleApplicationSupport.msi (or AppleApplicationSupport64.msi if you have a 64-bit system)
5. Choose "Repair" if you are prompted (if you are not prompted that's fine, too)

Your iTunes installation should work now. If you encounter problems using the steps outlined above, please leave a message in the comments below.
