I just upgraded from Free HTML Editor to HTML Editor. I tried and failed to uninstall Free HTML Editor first; Windows 10 (Pro v2009) told me it "couldn't open INSTALL.LOG file". So I went ahead and installed HTML Editor anyway, figuring it would probably install over the top. But it didn't. Now I have an installation of HTML Editor whose folder (D:\CoffeeCup Software) includes the Free HTML Editor installation (D:\CoffeeCup Software\CoffeeCup Free HTML Editor)

. I tried to uninstall HTML Editor and start over and I got the same error message. So now I have a free copy and a paid copy and I can't uninstall either of them. All I want is to uninstall both and reinstall just the paid version, but I do want to be able to uninstall it!
(I can find both INSTALL.LOGs; they are in the respective installation directories. So it seems the Wise Installation Wizard is not wise enough to be able to handle any install location other than the default one.)
