I just noticed that I have two versions of Calibre on my computer. This must have happened when Calibre stopped defining the 32 or 64bit downloads because of the whole "We stopped supporting Windows 7" and I downloaded version 4.7. I had the 64 bit version 4.6. So now I have the two versions.

Before anyone suggests why don't I switch over to Windows 10 or another OS, I am using Windows 7 because Windows 10 requires me to keep an external usb source for previous versions or restore points instead of storing them on the hard drive. I am not prepared to do this. I am not prepared to lose a usb port, or keep another drive tethered to my computer, which I move around all the time.

So my question is this, should I remove the older version or keep both, and will clicking on one version over another cause problems (outside of what the program would have beeing on the Windows 7)?
