To see if it's working open a command prompt.
Then run:
rtl_test
You should see an output similar to this:
Found 1 device(s):
0: PROlectrix DV107669
Using device 0: PROlectrix DV107669
Found Fitipower FC0012 tuner
Supported gain values (5): -9.9 -4.0 7.1 17.9 19.2
Info: This tool will continuously read from the device, and report if
samples get lost. If you observe no further output, everything is fine.
Reading samples in async mode...
lost at least 12 bytes
If so your dongle and driver are now fully installed.
Potential Errors
'rtl_test' is not recognized as an internal or external command, operable program or batch file.
If you used the installer, first change to the installation directory, otherwise you're PATH hasn't been set properly, try step 2 again.
- rtl_test reports 'No supported devices found.'
The driver has not been installed, try steps 3 to 7 again.
- rtl_test keeps repeating
'lost at least'
Your machine may be too slow, try closing other programs and plug the dongle into a different USB port.

How to point rtl scaner use index 1 instead of 0 ?
Hi!
Hi!
If you start the scanner then click 'Edit -> Radio devices' you should be able to select the second device.
It might be worth unplugging all your USB devices, one at a time and running rtl_test, to see which one is interfering with the rtlsdr driver.
error loading librtlsdr
I first installed SDR#, ran zadiag v2.2.689 build 0 to install the driver - all OK. I run SDR# and it works fine.
I tried to install RTLSDR-Scanner v1.0.2298.18049. It fails with the above message. According to the on-line documentation the Windows installer is supposed to install all the dependencies. What am I missing?
Source computer is Windows 7 Pro, all Microsoft updates installed.
error loading librtlsdr
Did you use
rtlsdr_scan-windows-64bit.exe
orrtlsdr_scanner-setup-win32.exe
?What is the error you are receiving?
failure during start of rtlsdr_scan-windows-64bit_standalone.exe
I use RTL#, so hopefully all drivers are installed successful?
The device called: RTL2838UHIDIR and the driver, installed by Zadig and used by RTL#, was: WinUSB V6.1.
My system is Win 8.2 (64bit)
I want to try RTLSDR Scanner so i get the the file above and run it.
But everthiing i get is a window with a message that an import error (loading librtlsdr) occured.
I exspect that all files, needs for running under win, are included in the standalone version?
There is no different between standard user, run as or admin.
I also instaleld the visual c++ 2013 runtime (without change).
Please be so kind to give me a step by step instruction what i have to do to run the software successful.

Have you added RTLSDR driver to your path (the x64 directory)?
OK, i copied the files (x64
OK, i copied the files (x64 folder) downloaded fom osmocom (RelWithDebInfo.zip) into the folder whre i run the standalone.exe from.
It looks as it is running, first scan was done!
OK, i copied the files (x64
Lovely, glad it works. Hope you find it useful.
Zadig device not found
Hi! Thank you for this great material!
I get stuck in the Zadig step: I find 8 devices with Zadig but none is Bulk-in. Could you please help me out?
Again, thank you very much.
Kind regards,
Fernando.
Zadig device not found
Thank you.
In the options menu of zadig have you selected 'List All Devices'?
I don't have the Bulk-In
I don't have the Bulk-In option either.
I don't have the bulk in
I don't have the bulk in option, but I do have my rtl dongle as an option so I used that, but when I do the test I get the error: not recognized as internal or external command. I've done step 2 multiple different ways and nothing seems to work...Thanks!
I don't have the bulk in
It sounds like the TV driver may be installed, try uninstalling it and run zadig again.
zadig timesout!
After setting the options to list all devices, I DO see the proper interface, however, when trying to install the driver, I get no success or installation of driver warning!
It just talks to me (like no one else does might I add) and then times out;
Oh, dear; please help me!
how i fixed Import error: Error loading librtlsdr.
I followed the installation instructions, however, I would get the following error when starting RTLSDRScanner:
Import error: Error loading librtlsdr. Make sure librtlsdr (and all of its dependencies) are in your path
I would get the following when running rtl_test
C:\Users\userX>rtl_test
Found 2 device(s):
0: , , SN: ⁿ
1: Realtek, RTL2838UHIDIR, SN: 00000001

Failed to open rtlsdr device #0.
I solved it by installing the WINUSB driver for the Composite device in Zadig as explained in https://www.reddit.com/r/RTLSDR/comments/6fhdns/windows_failed_to_open_r...
