Which version of'Virus TI Software Installer' is better?

Hi everyone.

I'm newbie to VIRUS TI2 world. I'm going to buy access VIRUS TI2 Keyboard
(perhaps I'll get chance to buy the Whiteout Limited Edition the one of the 150 units).
The life will show what's gonna happen.

Anyway, after buying that I have to change MAC OS (the previous owner) to PC OS one.

So, the question is which version of'Virus TI Software Installer' is better?
I'm using the 'Image-Line FL Studio 12 Producer Edition'

Here's the list:

Virus TI Software Installer_v40501_x64
Virus TI Software Installer_v41105_x64
Virus TI Software Installer_v45300_x64
Virus TI Software Installer_v50800_x64
Virus TI Software Installer_v51100_x64

I mean, which one is more stable and really tested by the users?

Thanks in advance.
