Whenever I try to upgrade to 1607 (tried it more than 10 times now), the upgrade ends unsuccessfully at, say, 93% finished with a message 'upgrade could not be completed - aborting' (not exact wording). Win 10 keeps coming back, nagging me to upgrade - to no avail. I have tried "everything": Check Disc and other disk clean up tools, completed several recommended Registry and Command Line procedures, removed external devices, updated misc. drivers, turned off antivirus (AVG), installed using MS Media Creation Tool. I try to avoid a clean install, because I have a few applications which are cumbersome to reinstall.
Are there log-files which would the cause(s) for update failures?
My PC is a plain DELL VOSTRO desktop with no special hardware installed, except for a Firewire card and a second harddisk.
