Manual Installation of SDR#

Manual Installation of the RTL-SDR drivers with SDR# for the RTL-SDR

1) Download the RTL-SDR Drivers, and extract the files from the x32 folder into the SDR# folder, replacing any files if it asks: (original link seems to have died recently)

2) Download zadig and place it into the SDR# folder:

    I can’t install the driver for my NooElec R820T SDR & DVB-T NESDR Mini on my Windows7
    The USB ID: 0BDA 2838 00
    As device I choose: Bulk-In, Interface (Interface 0)

    In the Driver field is written: WinUSB (v6.1.7600.16385) => WinUSB (v6.1.7600.16385)
    i.s.o. RTL2832UUSB( => WinUSB (v6.1.7600.16385)

    What is my problem?

    The link to /trac/raw-attachment/wiki/rtl-sdr/ is not responding. Is the server up today?

    Installation is tricky but possible. Read the directions from the Quick Start Guide and follow them closely. Install your SDR# directory in C:\ not Program Files. When logged in as root, set that SDR# directory to have write permissions also (default read only). Then go into Norton or other antivirus and set an exception for your SDR# directory and all subfolders. It is key to make sure that the .bat installs properly. It seems the WinXP version zadig works in Win7 also.

    Not sure about Win10. It’s too new to support many programs and drivers so my sympathies. I’ll try it in a year or 2 when they work out the bugs and driver incompatibilities.

    Unable to get RTL-SDR to work after upgrade to WIN10. Worked on same PC using WIN7. There is no .bat file in the SDR# zip file. Loaded and ran zadig.

      What version of SDR# are you running? The latest versions come with the install-rtlsdr.bat file included in the zip, I just checked, it’s most definitely there.

      This page is to help you if the bat file won’t run on your PC for various reasons.

    Norton claims that pthreadVC2-w32.dll is an “Insight Network Threat and has been removed. There are many indications that this file is untrustworthy and therefore not safe.”
