I've gone to their tech support, they haven't helped.

It might have had something to do with uninstalling the v1 and installing v2, but that doesn't work this time. There's something I did the first time around that differs from this time. This occurs at every stage until everything is functional.Ī google for '690lc' shows stuff about antec. Check Device manager, which displays an unknown device '690lc' saying that the drivers are missing/botched.The install completes, but upon opening fan control software, I get 'Cannot connect to Fan control device. Try using the install disk, which contains the same installer as v1 on the aforementioned website.(Version 2, as my s/n is similar to the one on the website.)The install does not complete, gets to 'Creating Shortcuts' and then rolls everything back and cancels the install. Install the software from the website, because everyone says not to use the included disk.This time, nearly the same thing happened except I haven't done one thing that I did the first time, which prevents me from installing the software. The first time after a lot of messing about, I finally got the whole thing to work. While most things installed hiccup-free, one thing that caused problems both in the previous win7 install and current install is the 'Fan control software' for the Thermaltake Water 2.0 Extreme liquid cooler. This effectively uninstalls pretty much everything sweeping the leftovers into windows.old which I got rid of. Just upgraded my computer running Windows 7 enterprise 圆4 EVALUATION (10 day trial) to windows 8.1 pro 圆4.
