I uninstalled Scrivener, then reinstalled Beta 1.4 (for the history, see this thread: https://forum.literatureandlatte.com/t/can-we-uninstall-the-older-beta-version-after-installing-bet/10289/1) and again got two desktop shortcuts. One is labeled beta, the other beta 1.4
When I right click the desktop icons to look at properties, the difference is that one notes the date of first installation of Scrivener on my computer, the other the Dec 13 update. Both are identical in all other respects.
This time only 1 version of the program populates the list for Add or Remove Programs.
