    Hello guys,
    So im trying to install a program called Carsoft 6.5 which is a d iagnostic tool used for older BMWs and to use this program i need Windows XP. I have used VirtualBox to do this and installed Windows XP there and managed to get the files over to that virtual computer. But when i open the setup for the program and try to install it, I get a error/fault message as follows:
    16 bit MS-DOS Subsystem
    The NTVDM CPU has encountered an illegal construction.
    CS:056b IP:168b OP?e 4a 42 95 08 Choose "Close" to terminate the application

    What should i do to fix this? Is it because Virtualbox? Because the program was designed for XP and i dont get why i get this error. I also get it while trying to install it on Windows 10 using compability mode.

    You can not run 16-bit programs on a 64-bit OS .. you can try extracting the files on another computer and hope only the installer is 16-bit and the binaries are 32.

    Just get a real xp machine (preferably a laptop) for something like this. These softwares were pretty buggy as is.
