 Short story: with the next release, 2024c, we plan to make
substantial
 changes to our 64-bit Windows build (though mostly they will not be
 very visible to users) and we'd like to get as many people as possible
 to give the new build a try in advance of the release (currently
 slated for the week beginning October 21).
 As of later today, the snapshot on sourceforge labeled
 gretl_install-64.exe will be the NEW build. If anyone tries it, has a
 problem, and wants to revert, a "traditional" snapshot will still be
 available: 
Thanks, Allin - at the risk of stating the obvious, another way of 
reverting is to re-install the current gretl release 2024b.
cheers
