Flashing: driver cannot be installed by Windows 7

Hi,

I'm trying to running the flash.exe. I'm following the steps from the tutorial (https://www.openacousticdevices.info/flashing), and when I reach step 1(Download your platform's Flash application), after I downloaded the flash.exe,I clicked "here" to install the driver, no .inf files appear, but the code below.

Than I copied the code to a .txt file, and converted it to a .inf file. But it still couldnot install. I donot know what went wrong and I cannot continue de process.

I use Windows 7. So how can I download and install this driver?

Many thanks in advance.
