cannot start or run due to incompatibility with 64 bit versions of windows

    Question

  • I don't know if this is the correct forum but here goes:

    I have 2 computers both with Vista Ultimate

    Computer 1 has in Windows\system32 and file named Autoexec.nt

    Computer 2 has the folder Windows\system32 but no Autoexec.nt

    I am trying to run a program that shells out to Dos to run LHA.exe

    Computer 1 works

    Computer 2 does not work, I get a message " cannot start or run due to incompatibility with 64 bit versions of windows.

    I tried to copy the autoexec.nt from computer 1 to computer 2 but it would not let me.

    This problem occured in Windows XP and I had to put the autoexec.nt back in the system32 folder.

    I did find this article does this apply? http://support.microsoft.com/kb/933662/en-us

    Any suggestions???

  • Hi elleng,

     

    Thank you for the post.

     

    As I know, Windows Vista 64bit versions do not support 16-bit applications. If you would like to continue to run 16-bit applications on Windows Vista, you can either install Windows Vista 32bit or use this application in a virtual PC.

     

    In addition, the hotfix KB933662 is only available to Windows Vista 32bit.

     

    Hope it helps.

  • I'ms sorry but I don't understand all of this. 

    How can I tell if it is a 64 bit Vista or a 32 bit vista?

    Can you have both?

    Where do you get a 32 bit Vista?

    How do you run a Virtual PC?

     

    And what about the Autoexec.NT - why is this file on a Vista machine and not on another Vista machine?

    Thank you

  • Hi Ellen,

     

    Thank you for the response.

     

    To check if the system is 32bit or 64bit, please click Start, right-click Computer and click Properties.

     

    You can install either a 32bit or 64bit Windows Vista on a computer. It depends on the installation disk you use. The label of the Windows Vista disk should mention if it is 32bit or a 64bit. To install Windows Vista 32bit, you need a Windows Vista 32bit product key. It is the same with Windows Vista 64bit. When you buy a copy of Windows Vista, you need to clarify if you prefer a 32bit or 64bit version.

     

    Microsoft Virtual PC is a virtualization suite for Microsoft Windows operating systems. Generally, we cannot run 16-bit applications in Windows Vista 64bit. However, if you really need to run them, please install a Virtual Windows XP/2000/Vista 32bit PC on the system.

     

    For more information about Microsoft Virtual PC, please refer to the following site:

    You can click “Frequent Asked Questions” on the page to get a brief understanding of Microsoft Virtual PC.

     

    If anything is unclear, please feel free to let me know.

     

    Hope it helps.
