I second this sensible and constructive idea. I can understand that, for whatever reason, NCH hasn't managed this transition properly. These things happen. But the stonewalling is unacceptable and extremely ill-advised. NCH, there should be a statement from your CEO saying he understands how serious this is, how dependent we are on this software etc. There should be a palliative (such as a Windows key code to tide us over). There should be instructions on exporting data from Express Invoice. There should be a warning to unsuspecting customers buying the Mac version of Express Invoice that it is not in fact compatible with Mac (at least not with the current OS). There should be a credible projection as to when we can expect a Catalina compatible version--even if that date is painfully far away. And there should be some assurance that the upgrade will be free or quite reasonably priced for those who've just bought the most recent useless release under the natural assumption that it would work.
