How to resolve error This iPhone cannot be used because the required software is not installed. Run the iTunes installer to remove iTunes, then install iTunes again.

Thanks AKSlive. Unfortunately its not that simple. AppleMobileSupport always rolls back during installation thus not installing or uninstalling properly. It is reaching some point in the install process that makes it quit everytime. Even if I delete all directory's in ProgramData, Common Files, and Registry. They do not seem to make a difference.

Uninstall order is:

I believe this to be the problem. That being the usbaapl64( Plug and Play driver ) is not being installed due to some misconfigured setting? Not sure how to go forward with this one as reinstalling via the INF install method for drivers does not seem to correct the issue either. Going to test one more route.

Ok got it to work! Just I thought was the problem. Since it was a PNP package problem I had to flush the Install package for the mobile driver. This is what I did to correct it.

1.) Open a Command Prompt elevated as a adminatrator.

2.) Type without quotes: " pnputil -e > %userprofile%\desktop\pnp.log " ( This will show a log file on your desktop. Open it up and look for something similar to this )

Driver package provider : Apple, Inc. <-- This shows you its the Apple driver package, should be the only one. Very important! Do not remove if its anything else!!!

Driver date and version : 05/18/2015 6.0.9999.67

3.) Once you have the file name from above. Type in the command prompt that is still open: " pnputil -d oem1.inf ". This will delete the driver package.

4.) Once the driver package shows its successfully deleted. Uninstall all iTunes software starting from top to bottom of this list. They must be in this exact order!!!

Use the Control Panel to uninstall iTunes and related software components in the following order:

iTunes

Apple Software Update

Apple Mobile Device Support

Bonjour

Apple Application Support 32-bit

Apple Application Support 64-bit

5.) Once all of the iTunes software is uninstalled. Clean your cache by using CCleaner ( Slim build ). Once installed make sure these two options are selected specifically. Temporary Files, Old Prefetch. Once that is done " Run Cleaner ". Wait for it to be done and reboot your PC.

6.) Reinstall with a fresh setup file from http://www.apple.com/itunes/.

If all went well you will be able to see your iPhone connect as usual. Mine took about 2 min after the confirmation of allowing this computer to sync to your iPhone. Anyways hope this helps someone else it was annoying but hey! its fixed now! 🙂

The problem is it leaves behind a USB PNP apple driver. Removing it allows the installation to run like it should. They should really use a install package that checks for problems like this during the install process. If you have a "Microsoft" driver for oem1 check the others for a apple driver. oem1 is not your only option just an example.
