Hi All,
Just spent about 3 hours struggling to get the driver installed on my very old Windows Vista 32 bit system. A tad frustrating but I did eventually find the key so thought I'd share.
When I first installed the GUI and the drivers, all appeared well but after trying to pair my remote with the first key nothing worked, even after trying several remotes. My first clue that something was amiss was when I looked at the firmware version and saw that in the GUI it was labelled as v -16.-16. That didn't sound right! I then tried to force the firmware upgrade from the GUI to no avail (just hung each time). I then found the ZADIG utility on the forums here and from that GUI it all looked like the driver was properly installed. I could tell however that things weren't quite right as in windows device manager, the flirc interface have a yellow caution next to it. I then noticed that there was a 32 bit version of the driver in the dropdown in the ZADIG utility and on a hunch forced an install of that. Voila! Yellow caution went away and my remotes started to register.
So it seems that the Flirc installer installs the wrong driver for 32 bit windows systems. Not sure if this is a bug or something that went wrong with my install specific to my machine. In any case I hope this helps someone else with a similar issue. Now that I have it installed, Flirc is as cool as I hoped :-)
