I apologies for the late answer, i was busy upgrading my hardware and with life in general. 😉
DAO is a very old game, on old x86 systems a x86 executable could only address 2GB of virtual memory. This restriction was brought over to modern x64 bit machines if you don't make the old executable "Large address aware". After that the DAOrigins.exe can address 4GB of virtual memory.
A explanation and the tool to do that whit "DAOrigins.exe" can be found here.
Virus total scan of the "4gb_patch.exe from that link"
