I just bought a UMC 204. I installed the "UMC Driver 3.29 for Windows 7-10" with no problems, and restarted my PC. I see my device in the UMC Audio Control panel, and audio playback works (see pic below).
However, I can't upgrade the firmware on the device. I downloaded and extracted BEHRINGER_UMC_DeviceFirmwareUpgrade_v1.12.exe, then ran UMCAudioDfu.exe. This produces a a message saying "The driver DLL required to access the device is missing".
I don't understand this, because the UMC driver is installed and seems to be working. Am I supposed to install something else too?

At this point, you browse to folder where you expanded the firmware, choose the appropriate .bin file for your device (mine was umc204-96k_1-12_dfu.bin since I have the UMC 204 96kHz model), and hit Start. The upgrade should then proceed.
