"I never got it to work"
Easy to use, and gave me the link from which I eventually downloaded.
Did not work from CNET
I downloaded from CNET, tried to run it and nothing would work. I tried several times (with fresh downloads), then determined that what I had downloaded here was a special installer which was supposed to get a guaranteed malware-free download and install--if your server was not too loaded. If it did not function, the recommendation was to go to the original manufacturer's site (link given) and download from there. I did so and installed OK.
