Answer 1

       I had the same problem but managed to fix it with Amy ; the apple advisor. Here are the steps!
First of all, make sure you have the latest version of iTunes installed. You can download it from here. These instructions will NOT work for iTunes 8, 9 or 10 anymore. If you’re unsure, just uninstall iTunes then re-install with the latest files.
Next, you need to manually copy the Mobile Device Support directory from a working machine to your Windows 7 computer. Luckily, I have conveniently provided these files for you. You can download them here:
64-Bit iTunes 11.0.2: Please click here to download this directory for 64-bit Windows.
32-Bit iTunes 11.0.2: Please click here to download this directory for 32-bit Windows.
Once you download that file, you need to Unzip it to this directory. IMPORTANT: Make sure you unzip the CONTENTS of the zip file, don’t just copy over the zip file:
32-Bit: Unzip to C:\Program Files\Common Files\Apple
64-Bit: Unzip to C:\Program Files (x86)\Common Files\Apple
There are a large number of files in that directory, so it may take a little time, please be patient.
So, after unzipping, you should have a new folder “Mobile Device Support” in the Apple folder
64-BIT ONLY STEP: If you have 32-bit Windows, skip this step. It seems that Apple has put the “Drivers” in a separate location (don’t know why). You will need to download the drivers separately. Please click here to download the files for 64-bit Windows.
Once downloaded, you need to Unzip it to this directory. IMPORTANT: Make sure you unzip the CONTENTS of the zip file, don’t just copy over the zip file:
Unzip to: C:\Program FIles\Common Files\Apple
So, after unzipping, you should have a new folder “Mobile Device Support” in the Apple folder
Next, we have to merge the registry entries that will install the Apple Mobile Device service.
First, download the registry entries that I have provided for you here:
64-bit iTunes 11.0.2: Click here to download the registry entries for 64-bit Windows.
32-bit iTunes 11.0.2: Click here to download the registry entries for 32-bit Windows.
After you download the registry entries ZIP file, unzip it to your desktop and double-click each to install it. Say “Yes” to any prompts or confirmations about adding it to the registry. There are 2 entries, make sure you click BOTH and add BOTH to the registry.
Now, we need to install the correct driver for your iPhone / iTouch. Windows 7 incorrectly identifies the device  as a digital camera. To fix this:
- Plug in your iPhone / iTouch (don’t have iTunes loaded at this time)
- Go to Device Manager (Click Start, right-click Computer,  then click Properties. In the window that appears choose “Device Manager” on the left)
- Scroll down and find “Apple iPod” or “Apple iPhone” or “Apple iTouch”. It will likely be under the “Portable Devices” category.IMPORTANT NOTE: If your device is already listed under “Universal serial Bus Controllers” and not Portable Devices, you can skip these steps and go to Step 7.
-  Right-click the Apple device and choose “Update Driver Software…”
- Choose “Browse my computer for driver software” in the window that appears
-  It will ask you for a location; you want to Browse to this folder (location is the same in 32 and 64 bit Windows):
32-bit and 64-bit: C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers
- Click Next
- It should find the driver for your device; let it install that driver
Once you complete these steps, reboot your computer. Once you reboot everything should work exactly as expected!
