I use ImDisk (as a RAM disk) on two different Win 10 (1809) 64-bit machines with no problems, and I've just installed it on another machine (1809) and set up a RAM disk - all fine, no error messages (haven't tried the 'reboot' test yet).Are you using the correct (64-bit or 32-bit) version of ImDisk for the OS you are running?
