iTunes won't work after fresh install

Hi there,

after a fresh install of Windows 7 Pro, I just can't seem to get iTunes to work properly.

I have all my music backed up, so that's not a problem. After installing iTunes and wanting to open it, I already get the message that Apple Mobile Device Support has a problem, and that I should uninstall and reinstall iTunes. I do that over and over, nothing happened. Here's an overview of what I've tried so far.

• using WinRAR, I unpackaged the iTunes6464setup.exe and install all the x64 components individually. This allowed iTunes to start up, but freezes every time I connect my iPhone 6, which leads to a force close.
• I tried turning off automatic syncing by unchecking the "Prevent iPods, iPhones, and iPads from syncing automatically'' box, this didn't work.
• I tried making a new user account on my pc, same problem and did not resolve anything.
• I tried to connect my phone to another computer, this did work because that is the computer I used to temporary sync my phone while my actual computer (the one with the bugs) went into service which lead to the fresh install, this did work, but I want to change my default library with this computer.
• I also thought it had something to do with iExplorer, so I uninstalled that and all other iTunes components, reboot, and install iTunes again. This did not work.
• Then I went on a hunt to find older versions of iTunes which i know worked on this computer, but newer than iTunes 12.4, since that is the update required to support iOS 10. This...did not work.

Contacting Apple for iTunes support is a pain in the ***, cause it's an endless loop of going back to the Apple Support page.

Any more suggestions? Thank you in advance
