Latest Logitech Options Software

where can I download previous versions? can't find them anywhere. I need a previous offline installer, mouse has started acting up with latest update

So that was interesting...

I first read this thread about a month ago. I use a Logitech K400 plus wireless keyboard/trackpad combo with Universal Receiver on my HTPC. I was using Logitech Options software, and wasn't even aware of Options+. So I downloaded Options+, but when I installed it, it said the K400 plus keyboard was not supported in Options+. So I uninstalled it and stuck with Options.

Just a day or two ago, I noticed in this thread that a new Logitech Options was available, so I downloaded and installed it. It worked fine. Today, I got a notification that the Options+ software now supports the K400 plus keyboard. I downloaded and installed it, and it seems to be working fine as well.

During this process, Logitech Options was not uninstalled. When I opened it up after installing Options+, it said the K400 plus was no longer supported by Logitech Options. So I uninstalled it.

It looks like they may be trying to push some users toward Options+. I'm fine with that, as it looks like it's kept more up to date than the old Logitech Options was.

So I have installed the latest version of Options+, and although my MX2 shows up as being connected via BT, my keyboard (G613) does not. And when I attempt to add it, it just opens the Bluetooth settings panel, which shows both as already connected. This was the same on the older version that I had installed prior to updating..

Does this software not support my KB ? I looked thru the online FAQ's and release notes but could not find an answer...

TIA for any assistance

I don't believe it does:
