Inquiry was last updated February 28, 2015, so Windows 8.1 really should be supported (8.1 came on April 8, 2014). Other than that, yes, The company is alive - their Offline Explorer was updated just two weeks ago - but Inquiry is obviously no longer being maintained. One may want to know why it then is available in their cart? The answer is, because it >"can be installed and used without limiting its features for 30 days. If for any reason you are unhappy with your purchase, we offer a 30 days money back guarantee after your purchase."< But not after 10 years.
