Once again asking for assistance to use it on Win10_64bit. Dont really exspect that there is any because on the DosBox homepage Win10 is not listed anymore as compatible OS. This is part of the Microsoft policy to cut user rights, call that update or even worse "upgrade" in favor of spy and adware. In the dosbox forum it was stated that even VirtualXP has been killed and can no longer be installed on win10. So after the next patchday be aware. Part of this policy is that updates cannot be shut off anymore, even if the service is deactivated. Had to learn that the hard way, when uploading to OneDrive was interrupted by automatic updating with forced newstart. Sorry if you object, felt that this was necessary because it hits Fractint badly. Albrecht
