GoodReader USB Transfer Program

GoodReader (an iOS app) has a 32 bit windows program (GoodReader USB) that allows easy drag and drop transferring of folders and files between my windows computer and my iPad.

Upgrading to the newest 64 bit version of iTunes disabled the GoodReader USB transfer program. The program doesn't think iTunes is installed (because it only works with the 32 bit version). GoodReader hasn't upgraded the transfer program yet and I've been told they might not. I use this program several times per week and it's a hardship to loose its functionality.

I uninstalled iTunes, downloaded a 32 bit version of iTunes and tried to install it. Unfortunately, the install doesn't work. The install program essentially insisted that I needed the 64 bit version. I've reinstalled the 64 bit iTunes 12 for the time being. Is there any way to revert to the last version of iTunes that was running on my computer.

Alternately, is there another iOS app (similar to GoodReader) with as good a USB transfer program that lefts me drag and drop folders and files onto my iPad?
