When installing the RTL-SDR Radio Support Package, I see the following error:

There was a problem installing the third-party software. To resolve this issue, contact Technical Support

I also see the following inside of my MATLAB installer log file:

java.io.IOException: Input is not in the .gz format

This is a known issue. The download of libusb and pkg-config software fails during installation. However, if the software is downloaded manually, the installation proceeds without errors using these workflows:

For MATLAB R2016a, follow these steps:

Locate the folder where the software was downloaded. It should be under the "Downloads" folder under the folder "MathWorks\SupportPackages\R2016b\archives\3p".
In this folder locate libusb.instrset* folder.
Download libusb version 1.0.18 to this folder (MathWorks\SupportPackages\R2016b\archives\3p\libusb.instrset*) from "<https://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.18/libusb-1.0.18.tar.bz2/download>", replace the old file that was inside the folder.
In the "MathWorks\SupportPackages\R2016b\archives\3p" folder locate the pkg-config.instrset* folder.
Download pkg-config from "<http://pkgconfig.freedesktop.org/releases/pkg-config-0.28.tar.gz>" to this folder, replacing the old file as well.
Retry the installation of the RTL-SDR support package

For MATLAB R2016b, follow these steps:

Locate the folder where the software was downloaded. It should be under the "Downloads" folder under the folder "MathWorks\SupportPackages\R2016b\archives\3p".
In this folder locate libusb.instrset* folder.
Download libusb version 1.0.18 to this folder (MathWorks\SupportPackages\R2016b\archives\3p\libusb.instrset*) from "<https://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.18/libusb-1.0.18.tar.bz2/download>", replace the old file that was inside the folder.
In the "MathWorks\SupportPackages\R2016b\archives\3p" folder locate the pkg-config.instrset* folder.
Download pkg-config from "<https://sourceforge.net/projects/pkgconfiglite/files/0.28-1/pkg-config-lite-0.28-1.tar.gz/download>" to this folder, replacing the old file as well.
Retry the installation of the RTL-SDR support package
