I am one of those who lost Logger32.exe and recovered it from the most recent update files folder. Then it disappeared again. This time I went to its properties (right-click on Logger32.exe and select Properties) and changed it to Read-only (bottom of the little page that comes up). It no longer disappeared. Wait... Recently I tried to update and kept getting error messages about not being able to replace Logger32.exe, but it finally dawned on me: Remove Read-only property, update Logger32, and then set it to Read-only again. This clumsy solution seems to work. While Read-only is off, the update can take place, and with it on, whatever it is that is removing Logger32.exe cannot do that.
I eagerly await Logger65 (because, like me, Bob believes in QRO).
