Q: Installing/Updating iTunes 12.1.x 64bit Error 7

Every time I try to install or upgrade iTunes on Windows 7/64 to any 12.1 version, the Apple Mobile Device service fails to start every time. If I hit ignore, then let the install complete, I get a permanent "Error 7" message any time I try to start iTunes.

If I reboot, I get the same errors plus several other applications are broken and have to be reinstalled.

I've had to go back to 12.0.1 and now everything works fine again.

What have apple done to 12.1 since going full 64-bit?

I’ve seen this a few times.
Most of the there there is 2 version of the Apple Application Support a 32 and a 64 bit version.
Check the uninstall.
If that is the case remove iTunes, follow
Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8
https://support.apple.com/en-us/HT204275

After removing all the programs in the order listed, power cycle the PC.

Then
Install iTunes from
iTunes 12.1.1 for Windows (64-bit — for older video cards)

Best of Luck
