Around 4/1/18 Google dropped their original CAPTCHA program, for a new revised program to gain access to certain websites. Sometimes called reCAPTCHA. With this change additional hardware and software changes are necessary. I still use Windows XPsp3, (which is out of date and not supported.) What I have learned, gave me a working system: XPsp3, Opera browser version 36, Dual Core Processor (SSE2). I have been unable to find a combination which works with a single core SSE processor. The sticking point is mostly with the browser, as it relates to the operating system and processor.
