Well, I downloaded this programm to run Resident Evil (1996) setup,
that need Win 95 and also in compatibility version doesn't work 'cause it needs DirectX3a library and I can't find it.

So I mounted game directory correctly [ mount D d:\ -t CDRom ] and I saw all installer files with "dir" command.
When I ask to run setup [D:\Setup.exe] the response is "This program cannot be run in DOS mode".

I tried to change program to execute, building a new directory and trying to run another simple .exe program but is the same.

I read the guide and I can't find my error.

I use Windows 10 (64-bit) OS
