In the link I find three buttons to download:
f6flpy-x64.zip (in this download, there just files, without setup to install)
What I have to install, and the "f6flpy-x64.zip", how to use it?
You need the SetupRST.zip. Unzip the file and install .exe driver. Do not use f6flpy driver because this is already included on the operating system as part of the Windows installation package.
