In fact I’m keeping a local copy, in case Logitech changes their site again and dead-ends that version too.I have a ThinkPad T450s which has been working flawlessly in Fedora 29. All I know is that if this happens again I’ll go straight to that earliest version of the Connection Utility and not mess around with the later revisions. Everyone’s system is unique and it’s quite possible one of the other things I did - including uninstalling all Logitech gaming software and the G-Hub - was also critical in making this work. I couldn’t quite believe it when the very last one worked).Īs with much advice on the internet, I’m not going to use words like “simple” or “easy” or “guaranteed fix” here, because that’s just frustrating for those it doesn’t help. ![]() (Of course I found this out the long way, having downloaded each and every other version and tried them one at a time. One power toggle on the mouse later and everything started working again. It detected the receiver straight away and offered to pair, where all others had reported no device connected. It’s the only version without a revision number in its filename. The key in the end was to click “Show All Downloads” when on the Logitech Connection Utility page and to download the VERY EARLIEST VERSION, version 2.00.3 from. I tried everything, uninstalling, rebooting, using different USB ports. More specifically the Connection Utility consistently refused to accept that a receiver had been connected, even though Task Manager was showing USB Receiver and/or HID-compatible Mouse whenever it was plugged in. Everything I tried on here failed initially, not least because Logitech’s own support pages are a nightmare and regularly send the user around in loops or to dead pages. Just a quick FYI that might help anyone struggling to pair a G602 mouse with a non-unified receiver under Windows 10. If it still won’t connect and you are using the right mouse with the right receiver, feel free to drop a comment below, post in the groovy community help forum, or call Logitech customer support 1-64. A window like the one in the screenshot above will open in fact, it’s identical to the regular pairing window, but using this one will create a new instance of the pairing process. This action will bring you to a new window here, select Pair a New Device. In the connection utility, go back to the Welcome screen and click Advanced. When pairing fails, Logitech suggests that you contact their customer support – but there is more thing you can try first. Voila, the mouse should now be paired with the receiver. Just turn off your mouse ( or take out the batteries) and then turn the mouse back on. Instead, click the Next button on the welcome page, and the tool will tell you to plug in the new receiver after that, you’ll reach the pairing screen. ![]() Don’t worry – it doesn’t install anything. Once you’ve downloaded the Logitech Connection Utility ( logitech_connect.exe), then go ahead and launch it and open the application. Note: The connection utility does not support Mac computers, so you will need to download the SetPoint software if you are running a Mac.
