OK, looks like it's time to just forget the appimage file. The next thing to try is the Etcher exe (executable file) on Windows 10. Try the link Judge posted above, click "Download (EXE)" if not, here is the direct download link:On Mint 17, the 64 bit version just closed the whole file viewer opened one way, and went back to selecting a drive and nothing else when opened the other way. Maybe I just don't know what command I'm looking for, but I sure don't see anything about "bootable." On Win 10, it just offers to look for something in the MS store that might open it. Does "appimage" mean it is still compressed?
It is taking a long time for my gumption tank to re-fill on this job.
