How can I start Zadig software for setup if it doesn´t start automatically?

Hello. I am installing the RTL-SDR package on a Windows 10 machine (Matlab R2017) through the instructions here. The first problem is that the Zadig software does not run automatically after plugging in the rtl-sdr dongle, I assumed this was probably because it is already installed. I can hear a tune from Windows when I plug in the RTL-SDR, but nothing else happens.

So I opened Matlab and ran the RTLSDR radio support package installer. At the "start Zadig Software" step, I got the message: "Cannot CD to C:\ProgramData\MATLAB\SupportPackages\R2017a\3P.instrset\zadig.instrset\zadig (Name is nonexistent or not a directory)." I tried to verify this, I ran a tree /f /a in C:\ProgramData\MATLAB\SupportPackages\R2017a and found a few folders named zadig.instrset:

+---appdata
|   +---3p
|   |   |   component_display_name_map.txt
|   |   \---win64
...
|   |       +---rtlsdrsrccode.instrset
|   |       |       rtlsdrsrccode.instrset_install_info.txt
|   |       \---zadig.instrset
|   |               zadig.instrset_install_info.txt
...
|   +---components
|   |   +---3p
|   |   |       zadig.instrset_win64 1498241327 2864172490759620334.xml
...
|   +---files
|   |   +---3p
|   |   |       zadig.instrset_win64 1498241327_manifest.bin
+---toolbox
|   +---local
|   |   +---instrset
|   |   |   \---zadig.instrset
|   |   |           win64.xml

the file "appdata\3p\win64\zadig.instrset\zadig.instrset_install_info.txt" has only one line stating

\ProgramData\MATLAB\SupportPackages\R2017a\3P.instrset\zadig.instrset

Wich is the non existent directory. Should I change it to a different location? How can I find it? But the 3p.instrset folder is in fact missing. Is there a fix for this? I´ll add the whole tree as an attachment. I have tested different RTL-SDR dongles to check for a hardware issue. The behaviour is the same in both devices.

I uninstalled the support package and retried from zero. Again, the zadig installer did not run automatically.

So I downloaded the latest version of zadig at http://zadig.akeo.ie/, and it found the 'RTL2838UHIDIR' device. I reinstalled the driver (meaning it had been previously installed).

After that, the process went smoothly.
