I got past the error message when it wanted me to insert disks. The problem was Norton - which I removed (bloatware). However, I am now just unable to play the game.
1. Download the zip file
2. Extract the zip file to local drive
3. Run the Deathlord executable (DeathlordRelorded.exe)
3.a. Get past the Windows Defender prompt (only asks me the first time)
4. I get the Apple ][ 'beep' and a twisting cursor that won't go away (waited about nine minutes while I made a grilled cheese).
And here it stays indefinitely (until I go to File and Exit)
I have tried running as "Administrator" and that doesn't give a different result.
