After the latest Windows 10 update (2004), my UR 44 would not connect (the light continuously blinking). So I downloaded the latest driver and installed it. It went through the motions, but did not appear in Device Manager! I tried to install it on 2 other Windows systems with the same result. Installation starts and ends, but it does not appear in Device Manager! So obviously, my system does not see my UR44!!! Any suggestions?
