Author: UPMOST

Question 1

Install fails or driver is blocked?

Accepted Answer

Run the UPMOST installer as administrator and use the correct 32/64-bit package. On Windows 10/11, check that the RTL2832U BDA driver is signed; if setup still fails, remove any previous driver package in Device Manager before retrying.

Question 2

Device not detected?

Accepted Answer

Connect the receiver directly to a USB 2.0 port, not a hub. Check Device Manager for unknown/USB or BDA entries, then reinstall `rtl2832ubda.sys`. Confirm your TV app is selecting the UPMOST DVB-T tuner, not another RTL2832U device.

Question 3

Version conflicts?

Accepted Answer

Old UPMOST software or generic RTL2832U/BDA drivers can override the correct package. Uninstall all RTL2832U entries and related software, reboot, then install the matching UPMOST driver. Avoid mixing Zadig/libusb drivers with BDA TV applications.
