This is why we are not working on two products because it will slow down the development of GenoProX which is already behind schedule. Besides, the reason we are writing GenoProX from scratch is precisely because the C++ code of GenoPro 2019 is 22 years old and needs a facelift. Trying to patch code which is 22 years old to add complex features, such as a real-time collaboration module (similar as Google Docs) is almost impossible.
When you buy GenoPro 2019, you get a credit of the same amount towards GenoProX. For instance, if you purchase a single user license of GenoPro 2019 at $49, then you will have a credit of $49 towards GenoProX. Since all licenses of GenoPro 2019 are permanent, you will always be able to use GenoPro 2019, even when GenoProX is available. We are not adding features to GenoPro 2019, however we will continue to patch it to ensure it runs on all OSes for the next decades. The first release of GenoPro in 1998 still run on Windows 10, so it is likely GenoPro 2019 will run for many decades on newer versions of Windows to be released. If not, we will fix GenoPro 2019 to make sure it continues to run smoothly on Windows.
